Abstract

PURPOSE: To enable to pick up the audio current two or more types without increasing the diameter of a record plate, by increasing the number of grooves on the record plate.
CONSTITUTION: As shown in figure, the height 2 made in parallel with the direction of revolution conventionally, has further the height 4 and the valley 3 orthogonally to the direction of revolution. Thus, the types of audio at the same diameter as conventional discs are increased and the multiplex of audio is made possible.
