The 4 track Cartridge
Despite having a cassette based format of their own (see below) RCA ignored it's potential as a car audio medium and instead repeatedly tried to market their 7″ records as the format of choice for car audio, despite numerous technical and practical disadvantages. This oversight presented an opportunity for smaller players to get into the market and that is just what a used car salesman from California called Muntz did in the early 60's, he was fed up with trying to get the car record players of the day to work so he decided to look for something that worked better. He found an endless loop cartridge called Fidelipack that had been invented in the early 50's but had not been able to find a niche, and promptly bought the patents rights to it. The original cart had been a 4 track mono cart, Muntz kept the format but used it in a stereo configuration. The resulting product was called Muntz Stereo Pak and became wildly popular in the southern USA as a car audio product. You can still get blank Fidelipack carts in the USA, while they are not intended for use in 4 track recorders they apparently do work, possibly an adjustment to the bias circuit of the recorder is needed.
wird ein fall für ebay ! :)
