Magnetic recording and reproducing control apparatus

Abstract

A magnetic recording and reproducing apparatus includes an input circuit for inputting the digital signal, an identification information addition circuit for adding recording identification information indicative of recording identification for the digital signal input through the input circuit, a recording circuit for recoding the digital signal with the recording identification information on the recoding medium, a reproducing circuit for reproducing the content of the recording medium, an identification information detecting portion for detecting the identification information from a reproduced signal reproduced by the reproducing circuit for ouputting an identification information detection signal indicative of detection of the identification information, a storage circuit for storing the reproduced signal, a time stamp detection circuit for detecting the time stamp from the reproduced signal stored in the storage circuit, an output control circuit for generating a timing for reading the reproduced signal from the storage circuit on the basis of the time stamp detected by the time stamp detection circuit, a reset circuit for resetting the output control circuit in response to at least the identification information detection signal, and an output circuit for outputting the reproduced signal read from the storage circuit, the identification information addition circuit adding the recording identification information to the digital signal for a given period where the recording circuit initiating recording on the recording medium, and the reset circuit resetting the at least the control circuit upon detection of the recording identification information from the identification information detecting circuit.
