Claims (1)

[Scope of utility model registration request] At the time of recording, a drive section and a recording/reproducing circuit section of a recording medium are controlled to a recording mode, and a servo phase of the drive section is controlled based on a synchronization signal in a recording information signal to record the recording information signal and control signal on the medium. In the recording and reproducing apparatus, the drive unit and the pre-recording/reproducing circuit unit are controlled to a reproduction mode during reproduction, and the servo phase of the drive unit is controlled based on an internally generated reference signal to reproduce the medium. an operation section having a force operation switch; and a control section into which an operation signal from the operation section and a reproduction control signal for the medium reproduced by the drive section are input, and which controls the drive section and the pre-recording/re-recording circuit section. , the control section is configured to control the drive section to a reverse playback mode by operating the connection operation switch during recording to play the medium backward for a predetermined period of time, and to set the previous recording and re-circuit section to a recording signal output mode. means for controlling and outputting the recording information signal to the outside, and controlling the drive section and the previous recording recircuit section in a reproduction mode to reproduce the medium after completion of the backward reproduction for the predetermined time; By operating the connecting operation switch during this period, the recording/reproducing circuit section is controlled to the memorization signal output mode to output the recording information signal, and the driving section is moved in reverse while counting the reproduction control signal a predetermined number of times. means for controlling the drive unit to a recording standby mode to play the medium backwards by controlling the medium to be in a playback mode, and controlling the drive unit to a recording standby mode after the reverse playback is completed during the period of counting the predetermined number; and the connection between the recording standby mode. Controls the drive unit into a continuous force playback mode while counting a predetermined number of the playback control signals by operating the replay operation switch, controls the servo phase of the drive unit based on the synchronization signal, and controls the pre-recording/re-recording circuit unit. A recording/reproducing device, comprising means for controlling the drive unit to a recording signal output mode to output the recording information signal, and controlling the drive unit and the previous recording/reproducing circuit unit to the recording mode after the connection and force reproduction mode ends. .
