Abstract:
A data recording and/or reproducing apparatus for recording and/or reproducing data for a recording medium having a sector including a servo area carrying servo signals used for servo and a data area provided in association with the servo area, comprising:a read gate; and control means for opening said read gate at a first timing associated with a timing reference signal recorded in said servo area to reproduce data from said data area if said timing reference signal has been detected with success; said control means opening the read gate at a second timing associated with a timing signal detected from within a servo area of a previous sector to reproduce data from said data area if said timing reference signal has not been detected with success; said control means when detecting a defective sector opening said read gate at a third timing different from said second timing if said timing reference signal cannot be detected to detect the defective sector of the recording medium.
