Patent number: 7920352Abstract: A magnetic disk apparatus that uses a head to write data in a plurality of unit areas arranged in an adjacent relationship to each other on a surface of a magnetic disk, and includes: a first recording section that records, in a RAM, the position of a unit area which is a target of data write; a first counting section that counts the number of times of data write operation performed for the unit area corresponding to the position recorded by the first recording section; and a second recording section that records, in a non-volatile storage medium different from the RAM, the side position which is the position of a unit area adjacent to the unit area whose number of records counted by the first counting section is more than a predetermined value.Type: GrantFiled: March 1, 2009Date of Patent: April 5, 2011Assignee: Toshiba Storage Device CorporationInventors: Hiroaki Inoue, Isao Suda

Publication number: 20010013989Abstract: For a balance adjustment due to a reduction in size and weight of an actuator, an arm portion, an axis attaching portion, and a coil supporting portion are arranged so that the centers of gravity on the coil side are located on a straight line connecting a rotational center and the center of gravity on the head side. Further, the improvement of an assembling efficiency of a VCM, an increase in torque, a one-touch fixing of an FPC connecting band, a noise prevention of a read pattern, and an insulation between the base and cover due to a bias of an MR read head are accomplished. A sector mark is detected by comparing a peak detection pulse and its reference polarity signal. A redundancy is provided to a reference detection polarity signal so that a read signal can be detected even if any one of the read signals of the sector marks is dropped out.Type: ApplicationFiled: April 24, 1998Publication date: August 16, 2001Applicant: FUJITSU LIMITEDInventors: MASARU SAIKI, TSUTOMU SASAKI, HIROKAZU ISHIZAKI, EIJI OKAMURA, TATSUYA GOFUKU, NORIHIKO SUZUKI, KOICHI TOHKAIRIN, HIROFUMI SUZUKI, KENJI ENDO, CHIHIRO ONO, KAZUHIDE OHBA, ATSUSHI SATOH, EISAKU TAKAHASHI, TAKASHI TOKAIRIN, ISAO SUDA, TAKAHIRO ONO

Patent number: 6137646Abstract: A disk apparatus has a disk medium with sector areas that have a servo area and a data area along the same cylinder. The servo areas also have a sector mark indicative of the servo area, a code indicative of a cylinder address, and a predetermined servo pattern to detect a head position, all magnetically recorded in the servo area. A disk control section uses a head portion to detect the head position on the basis of a read signal of the servo pattern and positions the head portion at an arbitrary cylinder to perform reading and writing operations. The disk apparatus also has a time measuring counter for starting to measure an elapsed time each time a predetermined position in the servo area is detected, and a time setting register for storing a time from a detection time point of the predetermined position in the servo area to the generation of the sector pulse.Type: GrantFiled: June 10, 1997Date of Patent: October 24, 2000Assignee: Fujitsu LimitedInventors: Eiji Okamura, Tatsuya Gofuku, Chihiro Ono, Kazuhide Ohba, Atsushi Satoh, Eisaku Takahashi, Takashi Tokairin, Isao Suda
