摘要：First to third grooves (Gv1, Gv2, Gv3) are formed in a magneto-optical disc. The grooves (Gv1, Gv2, Gv3) are adjacent to one another. The first and second grooves (Gv1, Gv2) are deep, and the third groove (Gv3) is shallow. The first and second grooves (Gv1, Gv2) are wobbling ones. Data is recorded on four recording tracks: the two deep grooves and two lands between the shallow groove and the deep grooves. The CTS signal is the sum signal (A+B+C+D) of a photodetector (6), and the push-pull signal is the differential signal (A+D)-(B+C) of a photodetector (8).
