Head displacement measuring method and apparatus and data recording/reproducing method and apparatus
Patent number: 6144516Abstract: In a head displacement measuring method, prior to actual data recording or data reproduction, either one of the recording head and the reproducing head is wobbled, and the test data is recorded in the disk-shaped recording medium by the recording head. Then, the test data is reproduced from the test data by the reproducing head, and displacement between the recording head and the reproducing head is detected on the basis of the reproduced test data. Thus, the displacement may be detected more easily with higher precision than with the conventional optical detecting method.Type: GrantFiled: March 28, 1997Date of Patent: November 7, 2000Assignee: Sony CorporationInventors: Toru Takeda, Satoru Seko, Takehisa Ishida -
Patent number: 6025969Abstract: A data for measuring deviation between a recording head and a playback head easily for correctly reproducing data despite such deviation. A playback signal amplitude detection circuit 23 detects the amplitude of playback signals of test data from a playback amplifier 15, while adders 51, 52 cumulatively sum the amplitude values of playback signals in a pre-set group of sectors and those in another pre-set sector of groups on a magnetic disc 21 supplied from the playback signal amplitude detection circuit 23. A subtractor 50 computes a difference between a first sum value from the adder 51 and a second sum value from the adder 52 and routes the difference to a controller 11. The controller detects deviation between the recording head and the playback head from the difference value. When recording or reproducing actual data, the controller 11 causes the position of the recording head or the playback head to be corrected on the basis of the detected deviation.Type: GrantFiled: October 2, 1998Date of Patent: February 15, 2000Assignee: Sony CorporationInventors: Hideaki Ishioka, Yoshikazu Onuki, Satoru Seko, Toru Takeda
