Servo regulating method of CD-ROM

Abstract

A servo adjustment method in an optical disc device. When a playback error occurs due to a defect in the optical disc during the playback operation, the servo adjustment operation is selectively performed again at the current position of the optical disc. A dialog box that requires the user to select a playback method; if the user selects the playback method as "still→jump→play", the operation of Still→Jump→Play will be performed repeatedly from the current playback position of the disc, and the playback operation will be realized according to the initially set servo value; if the user Select the playback method as "play after performing servo adjustment again", and perform servo adjustment again at the current position of the disc. When a playback error occurs due to a defect in the disc, although the physical properties of the inner and outer circumference of the disc are different, the servo adjustment operation can still be performed according to the physical properties of the position where the playback error occurs according to the user's choice, so that the user can still see all the playback images normally. .

Description

technical field [0001] The present invention relates to a servo adjustment method for an optical disc device, in particular to a servo adjustment method in an optical disc device that enables users to continuously enjoy playing images even if a disc reading error is caused by an optical disc defect. Background technique [0002] figure 1 It is a structural diagram of a common optical disc device (optical disc player; DVD player). The common optical disc device includes: an optical pickup 20 for reading recorded data on the optical disc 10; a rotary motor 21 for driving the optical disc 10 to rotate; a sliding motor 22 for driving the above-mentioned optical pickup 20 to move; a radio frequency signal processor (R / F) 30, the signal output by the above-mentioned optical pickup 20 is subjected to residual wave shaping and converted into a binary signal for output; the data signal processing part (DSP) 40, although the self-contained clock synchronized with the above-mentioned ...

Problems solved by technology

[0007] However, in the existing playback method as described above, there is a problem that as the still→jump→play operation is repeated, part of the playing video will be skipped, so that the user cannot see important video content.
