Abstract
An XY array of sync bits and information bits is recorded in a recording medium through the use of holography. The sync bits are in parallel Y-direction-extending groups having an X-direction minimum inversion interval of 2 or more. The information bits are placed between the parallel Y-direction-extending groups of the sync bits. One of the parallel Y-direction-extending groups of the sync bits and ones of the information bits neighboring said one of the parallel Y-direction-extending groups of the sync bits are scanned to reproduce a Y-direction sync bit sequence and at least one Y-direction information bit sequence. The reproduced Y-direction sync bit sequence is re-sampled through the use of a digital phase locked loop to obtain corrected Y-direction sync bit frequency and phase. The Y-direction information bit sequence is re-sampled in response to the corrected Y-direction sync bit frequency and phase. The Y direction is vertical, horizontal, or halfway therebetween.
