摘要： According to embodiments, a memory system includes a plurality of memory chips configuring banks, an instruction generator, and a memory controller. The instruction generator generates a plurality of instructions. The memory controller is configured to execute memory accesses to the banks based on the instructions. Each memory access comprises a first command sequence and a second command sequence. The first command sequence causes in-bank processing shortly subsequent to the first command. The second command sequence is executed subsequent to the in-bank processing. The memory controller executes successively a second command sequence to a first bank based on a first instruction and a first command sequence to the first bank based on a second instruction subsequent to the first instruction, and then starts a memory access to a second bank based on a third instruction while the first bank is executing the in-bank processing caused by the first command sequence.

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 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 non-recording regions.

摘要： A recording/reproducing apparatus includes: a rotary-type magnetic recording medium including a track pattern with concentric or spiral data recording tracks; a composite magnetic head including a reproducing element that reads magnetic signals from the medium and a recording element that writes magnetic signals on the medium; a control unit that moves the magnetic head over the medium to carry out tracking servo control on the reproducing element or the recording element to keep the element on a desired track; and a storage unit that stores offset information that specifies offsets for calculating an adjustment used to adjust a head position of the magnetic head during tracking servo control. The stored offset information specifies at least two different offsets per revolution of the medium. During tracking servo control, the control unit changes the adjustment at least once per revolution of the medium in accordance with offsets specified based on the offset information.

摘要： A magnetic recording medium enhances the quality of a reproducing signal. The magnetic recording medium has a servo pattern formed in a servo pattern area on at least one surface of a disk-shaped substrate by a concave/convex pattern having convex portions (recording areas) and concave portions (non-recording areas), and a data track pattern formed by the concave/convex pattern in a data recording area on the at least one surface of the disk-shaped substrate. In a state where recording data is not recorded in the data recording area, the convex portions in the servo pattern area are DC-magnetized, and the convex portions in the data recording area are AC-magnetized.
