摘要： A disk drive is disclosed which performs a head positioning operation capable of coping with a variation of an offset caused by a disk runout. A CPU of a head positioning control system calculates a second position offset amount by correcting a first position offset amount corresponding to a rotation angle of an actuator on a disk medium based on a disk runout amount. The CPU performs head positioning control including a position correction operation corresponding to a second position offset amount.

摘要： A magnetic disk adapted for use in a magnetic disk apparatus, which has a magnetic head with a pre-erase gap and a read/write gap with a predetermined spacing therebetween, and which uses a sector servo system to position the magnetic head onto a target track of the disk, is divided into a plurality of sectors each having an address field and a data field. A spacing gap having a length corresponding to the spacing between the erase and read/write gaps is formed at the beginning of each of the address and data fields. Servo information is provided at least in the spacing gap of the address field. The magnetic disk apparatus energizes the read/write and erase gaps at different timings, so that the initiation and termination of data erasing are performed prior to the initiation and termination of data writing, respectively.

摘要： A scanning image display includes a light source, a light detector, a scanning section, a storage section, a current controlling section, a reference current section, a sweep section, and a change section. The light detector detects the laser light emitted from the light source. The scanning section scans the laser light. The current controlling section controls laser light by supplying a current supplied to the light source. The storage section is configured to store a reference current value, a reference light output value, and a gamma table. The reference current section supplies the reference current value to the current controlling section. The sweep section sweeps current values supplied to the current controlling section to obtain one current value where the detected laser light corresponds to the reference light output value. The change section changes the gamma table based on the one current value obtained by the sweep section.
