Patent number: 7489460Abstract: A magnetic data read circuit includes a differentiation circuit and an integration circuit which are individually connected to a magnetic head, and a means of read judgment for pass/fail judgment on reading operation of magnetic data detected at the magnetic head. The read judgment means has first and second storage sections in which data relating to an output signal of the differentiation circuit and the integration circuit, respectively, are stored. The read judgment section obtains data from at least one of the first storage section and the second storage section and makes a pass/fail judgment on reading operation of the magnetic data. Such a magnetic data read circuit improves accuracy of reading magnetic data stored in a magnetic recording medium from a single transfer of the magnetic recording medium data.Type: GrantFiled: September 27, 2006Date of Patent: February 10, 2009Assignee: NIDEC Sankyo CorporationInventors: Ikuro Kuribayashi, Katsuhisa Higashi
