Abstract
According to one aspect, an optical recorder for recording data onto a disc includes a shock detector. The shock detector is used for determining whether the optical recorder is vibrated based on a servo error signal and generating a control signal. The control signal is used for interrupting recording data onto the disc when the optical recorder is vibrated.
Claims20
An optical recorder for recording data onto a disc, the optical recorder comprising:
- a spindle motor for rotating the disc;
- a motor driver for driving the spindle motor;
- an optical pick up head for emitting a laser beam to record data onto the disc and receiving a reflected laser beam reflected from the disc to generate a servo error signal according to the reflected laser beam;
- an optical pick up driver for driving the optical pick up head to move;
- a servo controller for receiving the servo error signal and controlling the motor driver and the optical pick up driver;
- a laser driver for driving the optical pick up head to emit the laser beam;
- and
- a shock detector for receiving the servo error signal and controlling the laser driver to stop driving the optical pick up head to emit the laser beam if it is determined that the optical recorder is vibrated based on the servo error signal.
An optical recorder for recording data onto a disc, the optical recorder comprising:
- an optical pick up head for receiving a reflected laser beam reflected from the disc and generating a servo error signal according to the reflected laser beam;
- and
- a shock detector for determining whether the optical recorder is vibrated based on the servo error signal and generating a control signal;
- wherein the control signal is configured for interrupting the recording of data onto the disc when the optical recorder is vibrated.
The optical recorder as claimed in claim 9, wherein the high voltage level is transmitted to the optical pick up head for interrupting the process of recording the disc.
A method for recording data onto a disc, the method comprising:
