<p>PURPOSE:To confirm the final field and to execute a consecutive recording with high accuracy by eliminating the slippage of the starting point at re- recording time by varying the level of the control signal of a recording final field. CONSTITUTION:The time constant circuit of a capacitor 11 and resistance 10 is used as the means for deforming the control signal of the last field, the plus side of the control signal outputs in the conventional waveform, the minus side is taken in a round waveform by the time constant circuit and the level recorded on a tape is reduced. During a temporary stopping the tape is rewound in its several feet part and when coming in a recording, then, the tape 1 travels with detecting the control signal in its several feet part by a control head 4. And in case of no minus signal within the stipulated timing after detecting the plus signal it is decided as the final field of the part recorded prior to a temporary stop and the recording is stared from the succeeding field.</p> |
