Abstract

1436161 Recording and playback systems BATTELLE DEVELOPMENT CORP 24 April 1973 00247/76 Divided out of 1435603 Heading G4M The recording and playback system of the parent Specification 1,435,603 has a synchronization circuit arranged to detect the presence of an unused binary data configuration such as one of the two binary values for a zero. The data is held in a shift register and if such a configuration is detected the data is successively shifted by one bit value at a time until the configuration is not detected.
