A recording/reproducing apparatus includes: 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; a recording head that writes signals on the medium; a reproducing head that reads signals written on the medium; and a control unit that controls the writing of signals by the recording head and the reading of 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 medium. The control unit writes the measurement signals using the recording head on first recording regions formed continuously in a radial direction of the medium out of the recording regions formed in the servo pattern regions, reads the measurement signals using the reproducing head, and measures the parameter based on the read measurement signals.
