ABSTRACT:
A system for recording and recovering analog signal in digital format utilizes a substantially video field format without the vertical blanking intervals thereby eliminating the need to time compress the information on a field by field basis. The digital signal is encoded for error correction of burst errors at least one line in length. Auxiliary digital information is substituted for particular lines of encoded signal for purposes of identifying the position of the playback transducer. The recovered signal is decoded by an error correcting decoder which recognizes the auxiliary information as a signal burst error and reconstructs the signal that was substituted by the auxiliary information. The decoded signal is then converted to a time continuous analog signal.
