ABSTRACT:
A holding device for holding a record (CD) in a magneto-optical recording/playback device includes a first wheel (R1) pressing against one side of the record. A first pivotable arm (AR1) supports a second wheel (R2), motion of the first arm moves the second wheel against the other side of the record and also centers the record in the holding device. A second pivotable arm (AR2) supports a magnet (M). A lever includes a third pivotable arm (AR3) mounted on an axis (A3) supported by the first pivotable arm and is in contact with the second arm. A fourth pivotable (AR4) arm pivots in a direction opposite from that of the third pivotable arm. A stop (AS) is in the proximity of the fourth pivotable arm. Accordingly, motion of the first arm (AR1) away from the record causes the third arm (AR3) to force the second arm (AR2) away from the record and also causes the fourth arm (AR4) to hit the stop (AS) and cause the third arm to move the second arm further and the magnetic head (M) away from the record.
