from the Editors

BEFORE ANYONE GETS too excited about the new cartridge development shown on the cover, and described by Dr. Goldmark beginning on page 32, it might be well to remember a few points. 1-the only machine available is a laboratory prototype model. 2-no firm has indicated that it will make its music available on these cartridges, including Columbia. whose laboratories developed the device under contract from 3M. 3-no machines will be available for sale until some- time in 1961. 4-tapes for the machine will require special duplication equipment which 3M is setting up in St. Paul. 5-this is a complete system of its own which is utterly foreign to any machine now in use. * * * * * * * * * * * * THE MACHINE appears to be designed for music, music, music. The cartridges are in a well, the mechanism is concealed by a cover. This would have to be removed for any splicing, etc. If the tape breaks in the cartridge you heave it in the ashcan. If it breaks outside the cartridge you can splice it in the regular way. Since the tape is Mylar this may be a moot point.

* * * * , * * * T * * * WE HAVE BEEN accused on some occasions of being anti -disc. Readers have suggested that since the disc has had a long and useful life that we let it die quietly instead of pushing it over the cliff. * * * * * * * * * * * * WE HAVEN'T BEEN anti -disc so much as we have been pro -consumer. We have nothing against the LP. It is ten years old, it works well. But the stereo disc is another matter. It was crashed on the market and the poor engineers have been fighting like crazy to make it better as it went along. This they have suc- ceeded in doing in some measure. The discs put out now are better than the first ones.

* * * * * * * * * * * M

A REMARK MADE by Dr. Peter Goldmark, head of CBS labs, during the press conference explaining the new cartridge machine seems largely to have gone unnoticed. He said "After six or eight playings the stereo disc deteriorates rapidly." He is the man who was primarily responsible for the invention of the LP record. We are glad to have such distinguished backing for what we have believed all along. * * * * * * * * * * * *

THERE IS NO question but that tape is best and since it costs only a few dollars more in the 4 -track form, or in some cases less than the stereo disc, the disc becomes an unwise purchase, if you want it to last. Tapes will sound the same ten years from now, they are a permanent investment.

* * * * * * T * * * * * SEVERAL PEOPLE at the press conference looked upon the new cartridge as the begin- ning of the end for the stereo disc, and well it might be. It could be that the public is so used to.thinking of recorded music in terms of discs that they want them even though they have heard that tape is better. If so, it is because this industry has not done the kind of promotion job it should have.

* * * * * * m * * r * * ALONG THIS LINE we are quite interested to note that Bell Sound systems has begun to promote its cartridge units which use the RCA type cartridge. Their units are very nice ones and so far Bel Canto, RCA and SMS are making music available to play on them. In order to help promote the units they are offering a deal for dealers which dealers should look into. They can get the scoop by writing to Bell Sound. * * * * * * * * * * * * AT THE SAME TIME, United Stereo Tapes is making tapes available to the distributors of records of those companies which also have a tape line through UST. * * * * * * * * * * * *

SO IT LOOKS LIKE YOU, the consumer, have a fat lot of goodies from which to choose.

Bottom: Find the end of the recording and play it just past the tape head. Cut the tape at this point. Below: To give you more room to work, remove the supply reel of tape and replace with the empty "loader reel."

Tape recorder specification: "Signal to noise ratio greater displease us or which interfere with what we want to hear than 50 db." are generally considered to be noise, even though in them- Before we get into an explanation of what this means to selves they might not be noise.

26 As we saw from a previous article, audio measurements are expressed in db's, which are the degrees on the audio man's thermometer. As you will recall, zero db was neither a loud sound nor a soft sound but one which could be heard pleasantly in a headphone. We also established the fact that the db scale is logarith- mic because that is the way our ears respond to sound. Most people cannot detect any change in sound level of less than 3 db, which actually is a doubling of halving of the sound, depending upon whether the sound is becoming louder or softer. Db ratings are rather easily converted to sound intensity ratios. All you need to do is add the number of zeros indi- cated by the first number of the db rating to the number 1. For instance, 30 db would mean 3 zeros following the 1, or 1000. 40 db would be four zeros following 1 or 10.000 and 50 db would be 100,000. Thus if you have a 50 db difference between two signals the actual difference between Photo by H. J. Hasbrouck A pure sine wave signal looks like them in terms of loudness would be 100,000 times. If there this on the oscilloscope. A dis- torted signal would be thickened due to harmonics interfering with were two signals with a 30 db difference between them, one the fundamental frequency. Distortion is easily seen by comparing would be 1000 times as loud as the other. the trace of the input signal to that of the output. While this difference may seem to be tremendous in terms of numbers, to the ears the difference is not so much signal being fed into the amplifier so that what went in, because you have to double a sound in db's in order to make comes out-but not the same. the difference apparent to the ear. This is caused by "off -beat" frequencies which combine The rustle of leaves will run about 20 db (100) above with the pure signal. For instance, suppose you have a 5000 zero db. A conversation runs about 60 db (1,000,000) and cycle per second signal that is pure sine wave.
