Patent number: 6765847Abstract: On a disk-shaped substrate with pits and grooves, a first dielectric layer, a magnetic layer, and a second dielectric layer are formed. A data region used for recording/reproduction includes a plurality of tracks, and is divided into a plurality of segments. Each segment includes a pit region and a groove region. Recording/reproducing tracks are composed of the grooves. Magnetic anisotropy of a magnetic layer positioned on each of lands between the respective recording/reproducing tracks is reduced to a level lower than that of magnetic anisotropy of the magnetic layers positioned on the grooves, so that the recording/reproducing tracks are magnetically separated.

Patent number: 6690626Abstract: On a disk-shaped substrate in which a predetermined region ranging in a radial direction is used as a data region for recording/reproduction, a first dielectric layer, a magnetic layer, and a second dielectric layer are provided. The data region includes recording/reproducing tracks composed of a plurality of discontinuous grooves or lands ranging from an innermost track to an outermost track. Magnetic anisotropy of each of magnetic layers positioned between the respective recording/reproducing tracks is reduced to a level lower than that of magnetic anisotropy of the magnetic layers positioned on the recording/reproducing tracks, so that the magnetic layers are magnetically separated only between the recording/reproducing tracks and not magnetically separated in flat portions without grooves. Thus, reflectance is even in the flat portions, thereby allowing tilt detection.Type: GrantFiled: April 18, 2002Date of Patent: February 10, 2004Assignees: Matsushita Electric Industrial Co., Ltd., Canon Kabushiki KaishaInventors: Masahiro Birukawa, Tomoyuki Hiroki, Yasushi Hozumi
