Controlling method and apparatus for feeding motor transfer of optical record player

Abstract

In this apparatus, every circle the CD rotates, the optical collector will move on the track with configured distance. Through the remained error on existed tracking driver, the dependence on the moving driver is minimized to compensate the remained error after the movement of the rotating information. Thus the moving error is rapidly compensated, and the remained error is minimized.

Description

(1) Technical field [0001] The present invention relates to the control method and device for the transfer of the feed motor of the optical record player, in particular to a feed transfer control method for a certain amount of feed transfer for an optical record player whose result is fed back and used for feed transfer control. A control method and device for motor transfer. (2) Background technology [0002] Generally, in the standard servo, only the tracking servo is used, and when the optical pickup tracks the eccentricity of the optical disc, due to the limitation of the drive range of the tracker, there will be a feeding error that the actuator does not track. Such infeed errors need to be tracked by the infeed drive. [0003] figure 1 is a schematic diagram of an ordinary CD-ROM drive system, figure 2 It is a structural diagram of the above-mentioned optical disk drive system. [0004] That is, in order to rotate the optical disk, the spindle motor generates rota...

Problems solved by technology

[0016] At this time, the feed and transfer servo driver 104 also occurs due to defects or disturbances. In the opposite direction of the feed and transfer direction, for example, the phenomenon of slipping from the track to the inner circumference or the outer circumference, therefore, the optical pickup can no longer be moved. To the inner or outer circumference, there is a phenomenon of spinning in place
