Loading operation
1. When a disk is inserted, the centering arm L or R
rotates, and the loading motor starts when SW1 is
switched from ON to OFF.
2. For a 12-cm disk, when the disk is carried to the
position of a dashed line, SW3 is set to ON by the
centering arm L, and the microcomputer judges the
disk to be an 12-cm one.
3. For an 8-cm disk, the disk cannot approach to the
position of a dashed line, and clamp operation occurs
as is.
(Centering arms L and R are coupled. But even if only
one side is pressed the arms cannot rotate beyond a
fixed width as the coupling part is locked.)
