Patent ID: 8503274

Claim:
An optical disc device that regenerates information data from data in an optical disc with the power supplied from a host device, comprising: a spindle motor configured to rotate the optical disc; an optical pickup having an objective lens through which the optical disc is irradiated with a laser beam, a tracking actuator configured to finely adjust a radial position of the objective lens relative to the optical disc, a focus actuator configured to finely adjust a vertical position of the objective lens relative to the optical lens, and a photodetector configured to detect light of the laser beam which is reflected from the optical disc and to read and convert the information data written in the optical disc into an electric signal to be output; a sled motor configured to move the optical pickup in a radius direction relative to the optical disc to determine a relative position; a servo unit configured to generate a drive signal used to finely adjust the position of the objective lens relative to the optical disc and to supply the drive signal to the tracking actuator and the focus actuator; a signal processing unit configured to process the electric signal output from the optical pickup, to supply the electric signal to the host device, and also to supply the electric signal to the servo unit in order to generate the drive signal; and a control unit configured to control the operation of the optical disc, wherein, when a power-on reset for re-starting the optical disc device is judged to have occurred after the optical disc device has been connected with the host device and started, but before the information data is regenerated, the control unit controls the operation of the optical disc device so as to reduce current consumption by the optical disc device.
