Patent ID: 7554760

Claim:
A recording/reproducing apparatus comprising: a magnetic recording medium on which data track patterns are formed in data track pattern regions by a pattern with recording regions and non-recording regions and on which servo patterns are formed in servo pattern regions by the pattern with the recording regions and the non-recording regions; a recording head that writes signals on the magnetic recording medium; a reproducing head that reads signals written on the magnetic recording medium; and a control unit that controls writing of the signals by the recording head and reading of the signals by the reproducing head and measures a predetermined parameter for at least one of the recording head and the reproducing head by writing and reading measurement signals on the magnetic recording medium, wherein when measuring the predetermined parameter, the control unit writes the measurement signals using the recording head on first recording regions that are formed continuously in a radial direction of the magnetic recording medium out of a plurality of the recording regions that are formed in the servo pattern regions and construct the servo patterns, reads the measurement signals using the reproducing head, and measures the predetermined parameter based on a result of reading the measurement signals.
