The stylus itself is egg-shaped or in other words, elliptical in shape with a long axis of the ellipse orientated across the groove in order to achieve good compliance. This can be identified as the ability of the stylus to track the groove and produce a linear signal. Whereas the tip of the stylus must be less than 0.025 millimetres in size that is normally made of industrial diamond. Stereophonic tape recorders were put on the market place two years before, and had proven to be commercially satisfactory which encouraged the production of stereophonic on discs. On the subject of the quadraphonic sounds on records: there is not much I can say here about an idea that never sounded any rhythmical vibes to the ears of the record buying public. In the early part of the 1970 quadraphonic records was introduced to the public. The quadraphonic is made up of four channels, as compared to the stereophonic discs two, the two extra channels was for the reproduction of atmospheric sounds; four rear left and right speakers. The real dilemma behind the malfunction of the quadraphonic in the marketplace was due the fact that corporations like Sansui, the Victor Company, CBS and RCA of America. They all inadvertibly confused the record buying public at large with dissimilar names in their description of the quadraphonic recordings. Instead of these companies getting their heads together in formulating a common pronouncement that would satisfy the record buying public and achieved a marketing value. In the past time Thomas Edison had a similar experience with his diamond phonograph due to his selfishness in creating a system incompatible with the competitor which put him out of business. |
