IPC: G11B21/10
Filed: 2001-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a data storage device capable of performing a track tracking operation even with respect to vibrations of a wide frequency with high accuracy. SOLUTION: A comparator decides whether or not the phase of an output signal of a digital peak filter coincides with the phase of a PES (position error signal) (step S103 of figure 8). If the phase of the output signal of the digital peak filter coincides with the phase of the PES, the frequency of the output signal of the digital peak filter is faster than that of the PES. Therefore, the set frequency of the digital peak filter is lowered (step S107 of figure 8). On the other hand, if the phase of the output signal of the digital peak filter does not coincide with the phase of the PES, the frequency of the output signal of the digital peak filter is slower than that of the PES. Therefore, the set frequency T of the digital peak filter is increased (step S105 of figure 8).
