  • Magnetic recording/reproducing apparatus for magnetically reproducing signals from one tape and recording the signals onto a second tape
    Patent number: 4887170
    Abstract: A recording/reproducing apparatus for transferring both information signals and address signals from one tape to another. A first tape is reproduced while monitoring the reproduced signal for the presence of address signals. When an address signal is detected, recording of the reproduced signal on the second tape is halted, and a new address signal corresponding to the detected address signal is generated and recorded on the second tape.
