機構。This is longer than the period required for the disc motor to rotate at a constant speed when started without a disc record attached.
A mono-multi circuit is set that is smaller than the period required for the disc motor to rotate at a constant speed when a disc record is installed and started, and is triggered by the playback command output, and is once driven by the playback command output. a disk motor, a constant speed rotation detection circuit that detects that the disk motor has reached a constant speed rotation state, and when the detection output of the constant speed rotation detection circuit is generated in a quasi-stable state of the monomulti circuit; A disk attachment detection mechanism includes a motor drive control circuit that generates an output that prohibits rotation of the disk motor.
