ABSTRACT:
A disk player system having a disk sucking function includes a disk sucking member of a configuration defining a suction space between it and a disk and a suction channel provided for communicating the suction space with an atmosphere about a center spindle or about a peripheral portion of the disk sucking member. A suction pump provided for sucking the disk is made detachable from a turntable so that a disk sucking operation is performed before the disk is played and the suction pump is detached when the disk is played. According to the system, deterioration of quality of the reproduced signal is prevented and a sucking efficiency is improved.
