Title: Magneto-optical recording and reproducing device
Inventor: ISHIBASHI HIROMICHI
IPC: G11B11/10
Filed: 1987-12-11
Abstract: PURPOSE:To prevent the occurrence of tracking off-set by detecting a second track position error detection signal from the output of a focus error detection and light-receiving means and providing a tracking off-set cancel means which takes a sum or a difference with a first track position error detection signal obtained from the output of the error detection and light-receiving means. CONSTITUTION:Track position error signals TE1 and TE2 are respectively detected from the track position error detection and light-receiving means 1 and the focus error detection and light-receiving means 2, and the tracking off-set cancel circuit 7 adds or subtracts both, whereby the non-uniform distribution of a light quantity on the track position error detection and light-receiving means 4, which occurs due to the double refraction of a recording medium 100 can be cancelled. Thus, tracking off-set can be prevented from occurring.
