    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.

    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： The present invention intends to provide a servo information writing system capable of writing servo information to an information recording disk received in a cartridge and having a relatively small storage capacity, without design modification of the disk and without decrease in storage capacity of the disk. To this end, the servo information writing system comprises: a disk loading portion for loading thereon an information recording disk received in a cartridge and for rotating the disk when the disk is loaded thereon; a hard disk to which clock information is written and which rotates together with the disk loading portion; a head disposed in proximity to the information recording disk as loaded on the disk loading portion to write servo information to the disk; a head disposed in proximity to the hard disk to exchange clock information with the hard disk; and a servo information forming section for forming servo information with the clock information read by the latter head as a cycle and supplying the thus-formed servo information to the former head.

    摘要： A tiltable pedal is assembled with a pin which is laterally welded to an accelerator lever. The pedal has two lugs formed with mutually aligned through holes. At least one of the lugs is further formed with a V-shaped slit which is contiguous with the through hole. The pin is laterally pressed through the slit into the through hole to allow tilting of the pedal about the pin. An end portion of the tilt spring is extended across the V-shaped slit to prevent the pin from moving laterally out of the through hole and through the V-shaped slit.

    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： Data track pattern regions, in which data track patterns are formed by concave/convex patterns, and servo pattern regions, in which servo patterns are formed by concave/convex patterns, are provided on a magnetic recording medium so as to be alternately disposed in a circumferential direction. At least one predetermined region that differs to the data track pattern regions is provided between two servo pattern regions that are adjacent in a circumferential direction. A concave/convex pattern including a plurality of first convex parts formed continuously in a radial direction is formed in each predetermined region.
