Abstract
The present invention provides an optical disc apparatus capable of rotating an optical disc with high speed while enabling reduced current consumption. The optical disc apparatus comprises a spindle motor for rotating the optical disc and a thread motor for driving an optical pick-up. When a command is received while the spindle motor is driven, a controller delays operation of the thread motor for a predetermined duration to allow operation of the spindle motor rather than immediately activating the thread motor. After the predetermined duration has elapsed, the controller activates the thread motor and halts the operation of the spindle motor. The predetermined duration may be either a fixed value or a variable value established so as to become smaller as rotation speed of the optical disc increases.
Claims20
An optical disc apparatus comprising:
- an optical disc driver for rotating an optical disc;
- an optical pick-up for recording/reproducing data to/from said optical disc;
- an optical pick-up driver for driving said optical pick-up in a radial direction of said optical disc, and
- a controller for controlling operation of said optical disc driver and operation of said optical pick-up driver, said controller delaying activation of said optical pick-up driver to allow driving operation of said optical disc driver when a request for activating said optical pick-up driver is made while said optical disc driver is being driven.
An optical disc apparatus comprising:
- a spindle motor for rotating an optical disc;
- an optical pick-up for recording/reproducing data to/from said optical disc;
- a thread motor for driving said optical pick-up in a radial direction of said optical disc, and
- a controller for controlling operation of both said spindle motor and said thread motor, the controller delaying activation of said thread motor and allowing operation of said spindle motor for a delay duration when a command associated with writing or reading is received while said spindle motor is being driven.
An optical disc apparatus comprising:
- a spindle motor for rotating an optical disc;
- a thread motor for recording/reproducing data to/from said optical disc;
- a controller for controlling operation of both said spindle motor and said thread motor, wherein when a command associated with writing or reading is received while said spindle motor is driven, said controller allows operation of said spindle motor for a predetermined time after receiving said command, and after the predetermined time has elapsed, said controller allows operation of said thread motor and halts operation of said spindle motor.
