  • Recording/reproducing method and apparatus for storing data in a memory after detecting errors in reproduced data from a magnetic tape
    Patent number: 6128147
    Abstract: An apparatus for recording and/or reproducing digital signals, such as PCM signals, as plural slanted tracks on a magnetic tape, includes a memory, first and second heads, a detection unit and a control unit. The memory stores the digital signals entering a terminal. The first head records the digital signals entering the terminal along with input address information. The second head is positioned on the downstream side of the first head in the running direction of the magnetic tape. The second head reads out the digital signals recorded on the magnetic tape by the first head along with the address information. The detection unit detects whether or not there is any error in the signal read out by the second head.
