<p>PURPOSE:To record continuously a code signal for a parameter such as absolute time by setting a relative speed and making it stable in response to a succeeding signal at the rewinding reproduction from a start point when new recording is started successively to a signal recording part formed already. CONSTITUTION:A sampling frequency 48kHz from the signal recording part of a magnetic tape is discriminated when the signal of the signal recording part is a signal of the 48kHz standard mode and the signal of the said mode is recorded succeedingly. The speed of a cylinder motor 15 is kept to 2,000rpm and a capstan motor 14 is set to the reproduction normal speed. The absolute time is read from the recording part during the reproduction period and stored in a memory in a control circuit 20. When the tape is fed up to the rerecording start point, the mode change from the reproduction to the recording mode is implemented by referencing the absolute time or the like and the absolute time is recorded continuously. In this case, the number of revolutions of the cylinder is unchanged and the signal is recorded in a consecutive normal code.</p> |
