摘要： A head gimbal assembly includes a magnetic head slider provided with a recording head element that applies a recording magnetic field to a magnetic recording medium and a suspension that supports the magnetic head slider. The magnetic head slider further includes a microwave radiation element that radiates a microwave magnetic field from a microwave excitation current that is supplied from a microwave generating circuit, and that applies the microwave magnetic field to the magnetic recording medium when the recording head element applies the recording magnetic field to the magnetic recording medium. The suspension includes a microwave transmission line that transmits the microwave excitation current, and the microwave transmission line is provided with a matching circuit to achieve impedance matching with the microwave radiation element.

摘要： On a magnetic recording medium, M sets of burst patterns are formed along a direction of rotation of a substrate in each burst pattern region. Each burst pattern is formed so as to include two types of burst signal units that have an equal length along a radial direction of the substrate. In a predetermined range (2·M) centers in the radial direction of the burst patterns are present at intervals of (1/N) times the track pitch in the radial direction. The predetermined range has a length along the radial direction of (2M/N) times the track pitch. M or N is a natural number of two or higher. The two types of burst signal units are formed of non-recording regions and facing end parts in the radial direction of the first type of burst signal units and the second type of burst signal units are separated via recording regions.

摘要： On a magnetic recording medium, M sets of burst patterns are formed along a direction of rotation of a substrate in each burst pattern region, where M is a natural number of two or higher. Each burst pattern is formed so as to include two types of burst signal units that are positioned at different distances from a center of data track patterns and have an equal length along a radial direction of the substrate. The length along the radial direction is (2·M/N) times the track pitch, where N is a natural number of two or higher. In a predetermined range where both ends in the radial direction do not match a center in the radial direction of a burst pattern, (2·M) centers in the radial direction of the burst patterns are present at intervals of (1/N) times the track pitch in the radial direction, the two types of burst signal units are formed of non-recording regions and do not overlap each other in the direction of rotation, centers of the burst signal units in the radial direction are separated by (M/N) times the track pitch, and facing end parts in the radial direction of the burst signal units are separated via recording regions.

摘要： A magnetic recording medium having high reliability is provided, in which concave portions between recording elements formed as convex portions of a concavo-convex pattern are approximately completely filled with a non-magnetic material. The magnetic recording medium is a plate-like body including: a substrate; a recording layer that is formed in a predetermined concavo-convex pattern over the substrate and includes recording elements for recording information formed as convex portions of the concavo-convex pattern; and the non-magnetic material filling concave portions between the recording elements. Side faces of the recording elements are inclined to face a surface of the plate-like body on a side toward which the recording elements 16 project in the concavo-convex pattern. An inclination angle of the side faces of the recording elements with respect to a direction perpendicular to that surface is smaller than 90° and 5° or more.

摘要： A magnetic recording and reproducing apparatus includes: a magnetic recording medium onto which servo information including position information is recorded by a plurality of concavo-convex patterns formed by a magnetic layer; a gate circuit that extracts a part of a reproducing signal of the concavo-convex patterns by removing an end of a signal corresponding to a concave portion or a convex portion of the concavo-convex patterns from the reproducing signal; a first integrator that obtains area integral of an extracted reproducing signal; and a second integrator that adds respective signals after area integral is obtained to each other to generate a position control signal for controlling a position of a magnetic head. Thus, the magnetic recording and reproducing apparatus can make an output of the position control signal larger and can perform positioning control for the magnetic head with high precision.
