Patent ID: 7660210

Claim:
A disk apparatus comprising: a loading mechanism for transporting a disk having data stored thereon to a predetermined position; a data position specifying mechanism for specifying a data position in the data stored on the disk; a motor shared between the loading mechanism and the data position specifying mechanism so as to produce a driving force for driving the loading mechanism and the data position specifying mechanism; a signal processor for processing a signal to control the data position specifying mechanism; a main controller for controlling operation of the apparatus as a whole; and a driver comprising: a motor controller for driving and controlling the motor; a data position specifying controller for driving and controlling a driving mechanism that is included in the data position specifying mechanism and that is driven by a driving force other than the driving force produced by the motor; a first signal input terminal via which a first control signal fed from the main controller to control the motor when the loading mechanism operates is fed in; a second signal input terminal via which a second control signal fed from the signal processor to control the motor when the data position specifying mechanism operates is fed in; a third signal input terminal via which a third control signal fed from the signal processor to the data position specifying controller is fed in; a control signal selector for selecting one of the first control signal fed in via the first signal input terminal and the second control signal fed in via the second signal input terminal and feeding the thus selected signal to the motor controller; and a selection control terminal via which a selection control signal is fed in by which the control signal selector is so controlled as to select the first control signal when the loading mechanism operates and the second control signal when the data position specifying mechanism operates.
