Abstract

PURPOSE:To realize an endless action with a simple structure, by providing a shunting means that ensures a shunt from a spiral groove of a pickup at the termination part of the spiral groove that turns in a body with a disk on which a magnetic sheet is mounted with positioning. CONSTITUTION:A disk 2 on which a magnetic sheet 1 is mounted with positioning, a rotary driving means of the disk 2 plus a spiral groove 2a that turns in a body with the disk 2 are provided. A pickup 9a is provided along the groove 2a and in a free displaceable way and energized toward the spiral groove by a spring 10 as well as to be reset to the original position by a spring 12. Then the sheet 1 on the disk 2 has the rubbing to a magnetic head 14 in coupling to the pickup 9a, and a downward slant part 2b is povided to shunt the pickup 9a from the groove 2a.
