Compatible disk player for playing multi-size disks and having a mode for selecting one disk type

摘要

The present invention relates to a compatible disk player, which is capable of playing compact disk CD or laser disk LD. More specifically, the disk player of the present invention reduces the delay time between loading and actually playing a disk. It includes a manual switch on the disk player, from which a person may select the type of disk to play, thereby decreasing the time needed to determine which type of disk is entered. If the CD mode is selected or the last disk to be played was a CD, the player pick-up is placed in the initial playing position of the CD before a disk is entered. After entering a disk, if it determines that an LD is loaded or the CD mode is cancelled (by the manual switch) the pick-up is moved to a ready position for the LD. By including a manual switch and circuitry which assumes the next disk type is the same as the last, the present invention reduces the time needed to determine which type of disk is loaded.
