Abstract
A data reproducing apparatus in which the identification information recorded in multiplicity on a recording track can be reliably reproduced assuring stable data reproduction including a decoder 61 to decode the area IDs supplied from an 8/10 demodulation circuit 43 and to supply each decoded area ID to counters C0 to C15, a system controller 70 to find the number of times of occurrences of coincidences of the area IDs of areas other than the end of data (EOD) area and, based on the frequency of detection of the occurrences of the area IDs by the counters C0 to C15, detects the area IDs of the (EOD) area. Finally, the system controller 70 controls the running of a magnetic tape 31 based on the detected area IDs.
