Embodiment Construction

[0019] figure 1 A schematic diagram showing a recorder control system 10 according to an embodiment of the present invention. The optical disc 11 has a plurality of spiral data tracks. The trimmer 15 judges the position deviation between the laser beam emitted by the read-write head 13 and the center of the data track according to the signal sent back by the optical sensor 131 of the read-write head 13, and generates a tracking error signal (Tracking Error Signal, TE) and focus error Signal (Focus ErrorSignal, FE). The radio frequency circuit 17 also generates a radio frequency level signal RF LvL according to the output of the optical sensor 131 , and transmits the radio frequency level signal to the controller 19 .

[0020] After the optical sensor receives the reflected light from the disc, it is converted into a radio frequency level signal by the radio frequency amplifier. figure 2 A schematic diagram showing the relative relationship between the optical disc and the ...

Abstract

The recording control method is for controlling the read / write head for whether to record data onto the CD. The recording control method includes the following steps: detecting the change of the amplitude of the state signal; and if the amplitude of the state signal is detected to have change and the RF level signal has amplitude change within specific range in certain time, judging as system vibration and sending out record interruption signal.

Description

technical field [0001] The invention relates to a method for controlling an optical drive; in particular, it refers to a method for controlling the recording function of the optical drive. Background technique [0002] Due to the advent of the electronic information age, the demand for high-capacity portable digital storage media is increasing day by day, and the storage capacity provided by the widely used floppy disk (floppy disk) in the early days is no longer sufficient. Therefore, optical storage media and storage devices with characteristics such as high storage capacity and portability are rapidly and widely used, such as optical drives (CD-ROM drives), recorders (CD-R drives, DVD-R drivers) and LD ( Laser Disc) player, etc. [0003] In the optical storage medium, the digital data is recorded on a disc-shaped optical disk (Optical Disk), which has a concentric spiral data track (InformationTrack), and the digital data is used in the data Sections with different opti...
