    摘要： An optical disk (D) is provided with multiple grooves (G) and multiple lands (L) alternating with each other. The address data recording regions have a pair of wobbling sections (31a, 31b) formed on both sidewalls of a groove (G) and having an identical phase. Thus, it is possible to obtain push-pull signals having a larger amplitude, which is advantageous for increasing the data recording density.

    摘要： A magneto-optical recording medium (D1) includes a soft magnetic layer (1), a groove forming layer (3), and a magneto-optical recording layer (4), successively laminated on a substrate (1). The substrate (1) is made of resin. At least a part of the surfaces of the substrate 1 held in contact with the soft magnetic layer (2) has a surface roughness of no less than 4 nm, thereby improving adhesion between the substrate (1) and the soft magnetic layer (2). Since the substrate (1) is made of resin, the production cost can be reduced.

    摘要： A magnetic disk apparatus includes a magnetic disk, a magnetic head, a reverse-pulse detector, and a re-magnetizer. The magnetic disk includes a data recording area and a servo-pattern area. The magnetic regions of the servo-pattern area have been pre-magnetized in the same direction or pre-magnetizing direction. The magnetic head is arranged to reciprocate radially of the magnetic disk. The reverse-pulse detector is provided for reading the servo-pattern area with the magnetic head before data recording or reproducing with respect to the data recording area is performed. The reverse-pulse detector detects, from servo reproduction signal pulses, reverse pulses corresponding to the reversal of magnetization direction relative to the pre-magnetizing direction. The re-magnetizer causes the magnetic head to perform the re-magnetizing of the magnetic regions in the servo-pattern area when the count of reverse pulses is not smaller than a threshold number.

    摘要： A magnetic disk apparatus includes a magnetic disk, a magnetic head, a servo reproduction signal generator and a magnetic head controller. The disk includes a data recording area and a servo-pattern area. The data recording area includes a non-magnetic area scattered with magnetic regions, and the servo-pattern area includes uniformly magnetized magnetic regions larger than the magnetic regions in the recording area. The magnetic head reciprocates radially of the disk, giving a magnetization direction to the magnetic regions in the data recording area and reading the magnetization direction of the magnetic regions in the data recording area and the servo-pattern area. The servo reproduction signal generator reads the servo-pattern area, using the magnetic head, via an absolute-value calculation circuit to generate a servo reproduction signal before the recording or reading with respect to the data recording area. The magnetic head controller performs recording or reproducing with respect to the data recording area by controlling the magnetic head based on the servo reproduction signal.

    摘要： A nanohole structure includes a metallic matrix and nanoholes arrayed regularly in the metallic matrix, in which the nanoholes are spaced in rows at specific intervals to constitute rows of nanoholes. The rows of nanoholes are preferably arranged concentrically or helically. The nanoholes in adjacent rows of nanoholes are preferably arranged in a radial direction. The width of each row of nanoholes preferably varies at specific intervals in its longitudinal direction. A magnetic recording medium includes a substrate, and a porous layer on or above the substrate. The porous layer contains nanoholes each extending in a direction substantially perpendicular to a substrate plane, containing at least one magnetic material therein, and is the above-mentioned nanohole structure.
