Abstract
Cell boundary ambiguities associated with data read from tracks of sequential cells from a data source such as a coded disc are avoided by incorporating specially coded cells in each track and sensing the status of these cells to determine the proper timing for enabling accurate readout from the track. The special cells are arranged such that data read therefrom is common at the bit cell boundaries but differs for at least a segment around the center of each bit cell. The specially coded tracks can be arranged to produce significant data as well as to control enabling of the data readout.
