Title: Timer recording system
Inventor: AKIBA NOBUO
IPC: G11B5/027
Filed: 1982-09-03
Abstract: PURPOSE:To avoid an interruption of sound recording signals, by erasing the signal at and after the forward tuning start position after the tuning is over in case the timer recording is reversed during the automatic tuning and then starting the sound recording at the backward side. CONSTITUTION:An arithmetic circuit 5 counts counter pulses P and makes a count memory 6 or a muting count memory 7 store the +1 or -1 count value in response to signals FWD and REV corresponding to the forward FWD or reverse REV tape traveling direction through a control circuit 2. At the same time, the circuit 5 checks whether the contents of the memory 6 are equal to the plus count or minus count or not in response to an end signal END which is generated from an automatic tuning processing circuit 3. Then a 0-count indicating signal 0 is sent to the circuit 3 in accordance with the result of above-mentioned check. The circuit 3 actuates an automatic tuning circuit 4 via the circuit 2 in response to the signal 0. Then the tuning signal of the forward side is erased, and a recording mode is started after inversion.
