するデイスクドライブ装置。 The transmission and reception of signals to and from the disk-shaped signal recording medium, in which tracking servo signals are embedded at predetermined pitches on the signal recording surface, is selectively controlled by the mode selection signal supplied from the host machine.When not selected, the signal readout circuit is turned off. In a disk drive device that is in a non-operating mode, the mode selection signal is supplied to one input terminal of an OR gate circuit, and the output cycle of the tracking servo signal is supplied to the other input terminal of the OR gate circuit. By supplying synchronized servo gate pulses and supplying the gate output of this OR gate circuit to the signal readout circuit, the signal readout circuit is put into operation mode during the servo gate period even when not selected, and the tracking servo is activated. A disk drive device characterized in that it is capable of operating.
