"off duty" 1970 - 1997 - eine Werbezeitung für's US Militär

Die in diesem amerikanischen (Freizeit-) Shopping-Magazin angeprie- senen Produkte waren auschließlich amerikanischen und kanadischen Militärangehörigen ausserhalb der USA zugänglich - also zu kaufen - vor allem zu ganz ungewöhnlich (verblüffend) niedrigen US $ Military-Preisen. Zu der einführenden "off duty" Seite geht es hier lang.

.

Unter dem Titel "Cartridges and Cassettes" finden wir fast alles ...... jedenfalls wurde es so angepriesen ... aus dem

Comsumer- und Nicht Hifi-Angebot bis zu echten Hifi-Geräten, jedenfalls wenn die Inserenten auch bezahlt hatten. Jeder Eintrag war "kostenpflichtig", mußte also gekauft werden, genauso wie die großen halb- oder ganzseitigen Anzeigen. Das war übrigens bei unserer Hifi-Stereophonie und den anderen deutschen Magazinen genauso. Alle diese "shopper survey's" waren in keinem Falle eine komplette (und wertneutale) Marktübersicht, als diese sie immer hingestellt werden wollten. Es waren gekaufte Einträge.

Diese Seiten müssten eigentlich ins Magentbandmuseum und dort ist der Unterschied zwischen "Cartridges" and "Cassetten" erläutert. Also Cartridges haben nur eine Spule im Gehäuse, Kassetten haben immer 2 Spulen.

Cartridges and Cassettes: In the Limelight

Who put those eight great tracks on that itty-bitty tape ? - This Month's Shopper - Off Duty / Europe / June 1972 - By THOM PRINGLE

About cartridges or cassettes

NEXT TO 4-CHANNEL, probably the most exciting thing on the audio scene today is the progress being made in tape recording - specifically, encased or unitized tapes. Unitized tapes, in the form of either cartridges or cassettes, have long been a source of fascination - the idea being to have a compact unit which could simply be dropped into a machine with no fuss or bother and high quality sound would be the result.

Actually, unitized tapes have been around a longtime. Remember the early RCA two-reel units that didn't make it? There have been several others, too, but our main concern now is with two types, the Philips-type cassette and the 8-track cartridge.

Der weltweite Vorteil der Philips CC Kassette

Although the Philips-type cassette has its shortcomings, one of the greatest advantages is the universal design of the cassette and the cassette players due to the perseverance and marketing pressure of the immense Philips company.

As a result, all cassettes today will fit all cassette machines - a fortunate situation considering the many designs which might have been developed with the multitude of different companies which manufacture cassette equipment.

Another advantage of the cassette is that it has two reels inside thereby allowing the user to reverse the tape direction to facilitate locating selections. Of course, at the end of the tape, the direction of tape movement must be reversed or else the cassette must be turned over.

Das Kassetten-Tape ist extrem schmal

In order to make the cassette small a narrow-width tape was designed which was much narrower than the standard quarter-inch magnetic tape.

To put four tracks on this tape for stereo use (two programs) the individual track width was reduced to 1/40". That's pretty small when you compare it to the 1/4" tracks used with "full track recorders" (wir nennen das Vollspur-Geräte) - about 10 times smaller.

And the problems which accompanied this exceptionally narrow track width included poor signal-to-noise ratio, alignment problems, and increased crosstalk - in other words, a real challenge for the audio engineers.

They were up to it, though, and came up with the now famous chromium dioxide tape, better tape heads, better tape handling mechanisms and, certainly not least, the Dolby System.

But just as they were patting each other on the back, the public started craving 4-channel and they were back at the drawing boards.

Die kompatible 4-channel Kassette

To design a compatible 4-channel cassette system involves the same problems as were previously mentioned in connection with putting two separate stereo programs on narrow cassette tape.

Only this time, the individual track width has been reduced to 1/100". Imagine trying to keep a moving tape in alignment so that it doesn't vary its vertical position more than 1/200"!

They've done it, though. The system has already been designed and tested, but there are some nagging problems which are preventing the systemfrom reaching the market.

With 4-channel growing in popularity, however, the problems connected with discrete 4-channel cassettes will be overcome or matrix encoding will be used, but in some manner you can expect 4-channel cassettes in the future.

Die 8-track Cartridge

Meanwhile, back at the ranch, the 8-track cartridge is happily spinning out 4-channel material without a hitch. Because the 8-track cartridge uses regular quarter-inch tape, its individual tracks can have a width of about 1/50" while still providing two separate 4-channel programs. Although it's not truly compatible, it's expected that people who buy a 4-channel cartridge will not expect to play it on a regular stereo machine.

In fact 4-channel may be credited with breathing new life into the cartridge since the cassette had been gradually taking over the unitized tape field.

With the advent of 4-channel, however, manufacturers started bringing out new cartridge units both for the home and for the car. So, you'll find several new cartridge units listed in our SHOPPER this month which have extensive features and are a direct result of the new interest in cartridges generated by the 4-channel boom. Not to mention that a bundle of prerecorded 4-channel cartridges have been produced and will be available to you as soon as the supply catches up with the demand.

Cartridges were losing favor because of their inherent drawbacks, mainly the inability to rewind, their larger size and the absence of a selection of playing times.

The cartridges with their single reel use a continuous loop principle where the tape is pulled from the center of the reel and rewound on the outside of the reel after playing. This necessitates a strong tape since the tape must not only withstand unusual twisting, but also must be used to pull the entire reel. Therefore, ultra-thin tapes are not used.

  • Anmerkung : Viele 8-Track Bänder waren auf der Rückseite extrem glatt, teilweise sogar "geölt" und das merkte man. Die 8-Track Kassetten haben durch die Bank weg gejault, was aber im amerikanischen Auto nie auffiel.

.

Die Zusammenfassung beider Konzepte

To summarize, before we get to the hardware, we can say that there are two types of unitized tape still very much in the picture; the cartridge and the cassette. The cartridge is a continuous, non-reversible, loop operating at 3 3/4 inches per second, for which there is equipment currently available to record and play back discrete 4-channel material.

The cassette is a two-reel unit operating at 1 7/8 inches per second with a terminated strip of tape which must be stopped or reversed at the end of the tape. Cassette equipment is not yet available for discrete 4-channel recording or playback.

Types of equipment.

Our SHOPPER lists two general types of equipment, portable and home-type (automobile units were covered in our April issue). Those units designated home-type will generally have a heavy case and will operate only from line power. The portable types will operate from batteries and have built-in carrying cases. As a rule, portable units are complete with amplifiers and speakers.
.

Sound modes.

Three sound modes are represented in our SHOPPER, monaural, stereo and 4-channel. Most portable machines are monaural with only a few stereo portables and no 4-channel portables as yet.

The home-type machines in this SHOPPER are mostly stereo units with a few 4-channel cartridge models represented.
.

Capabilities.

Generally, the machines in our SHOPPER can record and play back since people usually want to have both capabilities. Some models are playback-only models, but they are few in number. Models with and without built-in amplifiers are represented in our SHOPPER and we have identified them by calling the units with amplifiers (and usually speakers) "recorders" while the units without power amplifiers
are called "decks".

If you are looking for a portable machine, you will have little choice since almost all models have built-in power amplifiers and speakers. When selecting a home-type model, however, you will have to consider whether you wish to include the machine as an integral part of your hi-fi system or whether you want the unit to be able to perform by itself. Remember that even if a model has built-in power amplifiers it can still be connected into your hi-fi system thereby allowing you to use it in either manner.
.

Power output.

If you select a recorder rather than a deck you will find that the power amplifiers used are low-power units on the order of ten watts RMS per channel intended to drive high efficiency speakers. Therefore, if you want to drive an elaborate or low-efficiency speaker system, plan on feeding the line output of your recorder into an external amplifier to get the power you need. If you select a deck, of course, you're obligated to have an external amplifier and speakers.
.

Frequency response.

This is one area where great progress has been made in the field of unitized tapes. For a long time, the best frequency response with cassettes was from 50 Hz to about 12kHz. Recently, however, with improved heads and tape, the frequency response of high quality cassette machines has been pushed up to 16kHz - a very respectable figure in light of the obstacles which had to be overcome. This increased frequency response is one of the main factors for the sales which cassette recorders have stolen from open-reel recorders.
.

Signal-to-noise ratio.

Noise is that hissing sound you hear when you are playing a tape in your machine and the signal-to-noise ratio (S/N ratio) reflects how little of this noise exists.

This year, the entire S/N ratio situation can be summed up in one word, fantastic! In our open-reel recorder SHOPPER last September 1971, some of the most respected and expensive machines claimed a S/N ratio of 58 dB (the higher the S/N ratio, the better).

Now, however, as you look through this SHOPPER you will find some cassette units which, with noise reduction circuitry and chromium dioxide tape, claim a minimum S/N ratio of 56 dB which means that noise is no longer a real problem for the cassette. Unfortunately, similar progress has not been made with 8-track cartridges but chances are that improvements will be forthcoming.
.

Flutter and wow.

The flutter and wow figure is a good indication of the mechanical quality of a recorder. Flutter is the high frequency variance and wow is the low frequency variance introduced into the tape movement by a tape handling mechanism. The two are combined together and expressed as an average percentage which should be as low as possible - usually around 20 per cent.

Again, manufacturers have really pushed to improve the flutter and wow characteristics of cassette machines and many machines now boast flutter and wow figures less than 20%. Here also, cartridge equipment has not received as much attention as cassette equipment and, in general, the cassette units will have flutter and wow ratings which are a shade better than the cartridge units, but still not as good as the big open-reel machines.
.

Noise reduction circuitry.

Although there are still a couple of different noise reduction methods around, almost everyone agrees that the name of the game is Dolby. With only a few holdouts, every manufacturer has agreed to use the Dolby System and now prerecorded Dolbyized tapes are being produced, too.

Basically, a noise reduction circuit electronically processes the signal going to or coming from the tape in such a manner that the apparent noise level is reduced. Even though a cassette unit with noise reduction circuitry will cost more, it is recommended if you take your recording seriously. As yet, noise reduction circuitry has not been incorporated into cartridge equipment.

Tapes.

One of the most important factors in the improvement of cassette recorders has been the development of high performance tapes such as low noise-high output tapes and chromium dioxide tapes.

To use these tapes to their full advantage, however, the recording bias and equalization in a machine should be altered. Therefore, on many of the latest models of cassette machines you will find adjustments which allow them to be used with these new special tapes.

Some machines offer adjustment of the equalization or bias only, but it is preferable to adjust both. In addition, some machines offer adjustments for two types of tape, while others may be adjusted for three types of tape (regular, low-noise and chromium dioxide). Special tapes are not yet used in cartridges.
.

Head configuration.

Because of the limited space available for head entry in unitized tapes, only two heads can be used. Thus far, manufacturers have not produced models with multiple-function heads so that you can monitor the tape during recording but, rumor has it, these models are on the way.

  • Anmerkung : Später kamen echte Dreikopf-Kassettengeräte auf den Markt, es dauerte aber noch. Nakamichi machte den Anfang.

.

Special features.

Different manufacturers offer different features, some of which are very useful. Automatic shut-off is an especially helpful feature, allowing you to leave your cassette recorder unattended with the knowledge that it will release the drive mechanism at the end of the tape thereby reducing the possibility of damage to the tape or mechanism. Some mechanisms also have the capability of automatically reversing the tape direction at the end of the tape and playing the alternate tracks, while a few other machines are changers with the capability of handling several cassettes, changing them in sequence as each finishes playing.

The cartridge models all have automatic program channel sequencing which switches from one program channel to the next as the tape finishes one complete revolution. Some models also have an automatic shut-off feature which shuts off the machine after all tracks on the tape have been played.

Features somewhat standard include a selection of input and output connections, digital counters, program channel indicators and VU meters. Several cartridge models now have fast forward modes - very handy when you're hunting a particular selection on a cartridge.

Like so many other developments, unitized tapes started out as something of a toy. Cute little things that were fun to play with and no one took them seriously. Look at the specifications, features and many models in the following SHOPPER and you'll see that it's a different situation today.

Wir sind erst in 1972 und die Entwicklung schreitet voran.

Die meisten dieser CC-Geräte haben mit Hifi nichts zu tun, die ganzen 8-Track Geräte wegen des Jaulens schon gar nicht. Bei uns wurden die fast nur in Diskotheken als Jingle-Machines eingesetzt. Da spielte Jaulen überhaupt keine Rolle, laut und noch lauter war und vor allem "immer wieder aufs neue" angesagt. Die 8-Track Kassette konnte die Bänder endlos abspielen.

Und jetzt kommen die Preise.

Es beginnt bei sage und schreibe 18,33 Dollar, das billigste Teil, das es jemals gab. Und bei 247 Dollar hörte die damalige Luxusklasse bereits auf.
