ABSTRACT:
A bit error measuring apparatus in which bit errors in a rewritable information recording medium are measured by reproducing data after the data have been repeatedly recorded on the medium, in which position of recording data used in random number data generated in a memory is periodically shifted every time recording is performed such that not only different recording data can be repeatedly recorded at a predetermined area of the medium at high speed but bit errors can be detected at identical bit locations of the medium by reproducing data from the predetermined area only when the identical recording data have been recorded.
