ABSTRACT:
A disc player, for playing various information carrier discs, which includes, a single turntable for supporting an information carrier disc, a single drive motor for rotating the turntable, and a reproducing head device for reading signals recorded on the disc. The drive motor has a motor body and a rotation shaft, and is attached at its rotation shaft directly to the turntable with its motor body spaced apart from the turntable. Therefore, a clearance is formed between the motor body and the turntable. The reproducing head device is radially transferrable relative to the turntable. When the reproducing head device is transferred to its innermost position where it reads the signals recorded on the inner periphery of the information area of the disc, it is positioned in the clearance without butting against either the motor body or the turntable.
