Title: Signal recording checking device
Inventor: MATSUOKA HIROKI
IPC: G11B27/36
Filed: 1989-11-27
Abstract: PURPOSE:To automatically check the recording of signals by providing a delay circuit, matching the time bases of the signals before and after recording, comparing the time bases at all time sand detecting whether the signals are the same or not. CONSTITUTION:A delay arises between the signal before recording and the signal to be recorded and reproduced and, therefore, the signal before recorded on a VTR 10 and the signal after the recording are adjusted in the delay circuit 11 and the time bases thereof are matched. The levels of the two signals before and after the recording are compared at all times by a dissidence detecting circuit 12. The circuit 12 generates a dissidence signal when the signal from the circuit 11 and the signal from the VTR 10 do not coincide. The checking of the recording of the signals is automatically executed in this way by the absence of the dissidence signal at all times without using the five sense of man.
