ROTARY HEAD TYPE RECORDING OR REPRODUCING DEVICE

摘要

PURPOSE:To grasp the recording state of the entire area by dividing a tape type recording medium lengthwise into plural areas and deciding on the recording state of each area on the basis of the generation timing of the RF signal in the output of a rotary head. CONSTITUTION:The magnetic tape 1 is divided lengthwise into plural areas and an information signal is recorded in and reproduced from every area by rotary heads 3 and 4 which traces the tape 1 in its width direction. When the signal is recorded, a pilot signal for tracking from a pilot signal generator 23 is recorded together with the output of a PCM audio circuit 22 and when the signal is reproduced, a reproduction output is obtained from the circuit 22 and tracking is controlled by an ATF circuit 26. The RF signal in the outputs of the heads 3 and 4 is supplied to an area decision circuit 28 through a gate circuit 27 which is controlled with output pulses of a gate pulse generating circuit 17 and the circuit 18 decides whether each area is already recorded or not, so that the decision result is displayed on a display device 29. Thus, the recording states of all areas are grasped.
