Abstract

PURPOSE: To ensure an automatic and continuous performance of both surfaces of a record disk, by using a linear tracking arm.
CONSTITUTION: The end of performance of the upper surface of the record disk 3 is detected by a known means. And the guide 6 is slid and moved back to the chain line 6a. After this, the arm 5 is shifted along the guide 6 up to the lower face of the disk 3. At the same time, the rotation of the motor 4 is reversed to send the guide 6 back to the position of the solid line. Then the stylus of the arm 5 is applied to the lower face of the disk 3. The end of performance of the lower face is detected, and the guide 6 is sent back to the position of the chain line to be put on the upper face of the disk 3. Thus the performance is carried out on the upper face of the disk 3.
