A method and apparatus for eliminating errors in a seek operation on a recording medium are provided. Given a target address on a recording medium, a reading device is moved to seek the target address, and it is determined whether or not a signal is read out at the location to which the reading device has been moved. If the expected signal is not available at that location, by extending a variable frequency range of an oscillator clock of a PLL circuit or by increasing a track gap between the target address and the track to which the reading device jumps initially to seek the target address, the oscillator clock can be phase-synchronized to EFM signal from the recording medium reliably, resulting in reduction of the seek errors.
