ABSTRACT:
A laser disk record player particularly adapted for mobile applications such as in portable players and automobile mounted players. The player is provided with locking means for preventing free movement of the laser carrying scanning assembly when the player is switched off, thereby to prevent excessive wear or accidental damage caused by random acceleration of the normally free arm. With the record player in the load position, the locking means engages the scanning assembly to prevent motion thereof. When a disk is inserted and the player is switched to the play position, means are provided for automatically freeing the locking means thereby to allow the control circuit of the laser player to take over positioning of the arm.
