摘要： To make a magneto-optical disk to have higher track density and enable stable tracking servo to be performed thereon. On an magneto-optical disk, a first groove Gv1, a second groove Gv2, and a third groove Gv3 are formed so as to be adjacently arranged. The first groove Gv1 and the second groove Gv2 are deep grooves, and the third groove Gv3 is a shallow groove. Data is recorded on six recording tracks of these three grooves and three lands between respective grooves. A CTS signal is obtained by a sum signal (A+B+C+D) of a photo-detector 6, and a push-pull signal is obtained by a difference signal (A+D)−(B+C) of a photo-detector 8.

摘要： There are provided an optical disc and an optical recording apparatus to form a tracking groove onto an optically recordable disc. This apparatus comprises: a recording beam generator to generate a recording beam such as a laser beam having a predetermined spot size so as to form a pattern of a predetermined width onto the disc; a light deflector arranged on an optical path of the recording beam generator; and a driver for driving the light deflector for reciprocally moving the recording beam in a radial direction of the disc at a high frequency, and for multi-exposing the disc by the recording beam due to the movement of the recording beam in the radial direction, whereby a groove having a width wider than the pattern of the predetermined width is formed. With this apparatus, both the discrete information pattern and a groove are formed by using a single recording beam. Namely, both the pits and a wide groove can be formed by using a single recording spot.
