用新案登誠求の範囲第１項に記載のテープレコーダ。[Claims for Utility Model Registration] ■ In a tape recorder that records and reproduces audio signals by selectively driving a noise reduction circuit when recording and reproducing audio signals, recorded on a magnetic tape □ Forming a pilot signal for recording the drive discrimination pilot signal on the magnetic tape only when recording the voice signal by outputting a drive discrimination pilot signal having a lower frequency and lower level than the audio signal and driving the noise reduction circuit. a circuit; and a circuit that detects the drive identification pilot signal recorded on the magnetic tape when reproducing the audio signal recorded on the magnetic tape, and drives the noise reduction circuit to detect the recorded audio signal and the noise reduction circuit. Cheaply and Korg are equipped with a drive and motion discrimination detection circuit that distinguishes between audio signals recorded without drive. ■ A drive identification pilot generation unit that forms audio signals from stereo audio signals and multiplexed audio signals recorded on two channels of magnetic tape, and outputs a pilot signal for drive identification to the pilot signal formation circuit, and a noise reduction circuit. and a first switching unit that records the driving identification pilot signal on one channel of the magnetic tape only when recording both the audio signals respectively. The tape recorder described in . ■ The pilot signal forming circuit includes a low-frequency and low-level stereo signal having a frequency different from the frequency of the drive identification viroft signal, a stereo system that outputs a multiplex identification pilot signal, a multiplex pilot creation section, and a stereo audio signal and multiplex audio signal. When recording one of the two audio signals, the pilot signal for drive identification is recorded on the other channel or channel of the magnetic tape, and when the other of the audio signals is recorded, the pilot signal for stereo and multiplex identification is recorded on the other channel or channel of the magnetic tape. a second switching section for recording on the other channel of the magnetic tape, and detecting both the identification pilot signals when reproducing both the audio signals recorded on the magnetic tape, so as to distinguish between the stereo audio signal and the multiplexed audio signal. A tape recorder according to item 1 of the scope of the application for utility model registration, which is provided with a stereo and multiplex detection circuit for performing identification.
