Digital data logging reproducing arrangement and digital data logging regenerative manner

摘要

PURPOSE:To allow the device to generate a correct synchronization reference signal in the special reproduction mode and to provide an output of data so as to operate a decoder correctly especially in the reverse reproduction mode. CONSTITUTION:A special reproduction data generating circuit 1 generates auxiliary data packet from received digital data and a recording signal processing circuit 4 applies prescribed recording signal processing to the auxiliary data packet and the received digital data packet to generate a recording. packet, which is recorded on a magnetic tape 7. A reproduction circuit 8 obtains reproduction data from the magnetic tape 7 and forms again the received data packet from the reproduction data in the usual reproduction mode and forms again the auxiliary data packet in the special reproduction mode. A detection circuit 2 detects the presence/absence of a synchronization reference signal and its position in the special reproduction mode and a rewrite circuit 3 rewrites the detected synchronization reference signal so as to be in correct synchronization with a current special reproduction speed. The received data packet in the usual reproduction mode and the auxiliary data packet in the special reproduction mode are outputted externally.
