Abstract
In a video disc system wherein each data field includes, as well as a video signal, a predetermined digital start code followed by a digital error code and digital information bits, the error code is a polynomial division code chosen so that for each data field an error code remainder register in the video disc player initially contains the predetermined start code rather than zero, and/or, if no errors are detected, finally contains the predetermined start code rather than zero. An arrangement is also described which, in response to the reading of a particular sequence of data from the disc indicating the end of the record, disables the read head.
