A vibration extraction processing unit extracts a deflection component synchronous with a rotation from a clock signal of a non-contact sensor so as to correct a clock jitter. A clock generating unit generates a clock signal of any format frequency preliminarily set up according to the clock signal from the vibration extraction processing unit. A sector correction processing unit measures an error due to the frequency deflection so as to correct the writing start position for the format pattern signal of each sector containing a servo frame signal stored in a memory according to the measured error. Writing processing units read out the corrected format pattern signal from the memory according to a synchronous signal corresponding to a single turn of a disc and a format frequency clock signal and then writes into a disc medium face.

An oscillating apparatus includes a driver generating a waveform signal based on a stored data for specifying a waveform so as to output the waveform signal to a transducer. A detector detects a phase difference between electric voltage and current supplied to the transducer. A memory unit holds gain data reflecting a characteristic of the transducer. The gain data specify gains corresponding to respective phase differences. An arithmetic unit calculates the frequency of the waveform based on the phase difference detected at the detector and a gain included in the gain data. The oscillating apparatus enables determination of a gain suitable to the transducer in view of the characteristic of the transducer. The frequency of the waveform signal is allowed to follow the change in the resonant frequency in a shorter period. The oscillation can thus be kept well.
