Magnetic video and audio recording and/or reproducing apparatus for simultaneously recording input video and audio signals |
摘要 |
A magnetic video and audio signals recording apparatus for simultaneously recording video signals and two audio signals in first and second recording areas on a magnetic recording medium comprising a video signal recording structure for recording the video signals in the first recording area using magnetic heads A1 and B2, a first audio signal recording structure for recording an FM audio signal to be recorded obtained by at least frequency-modulating the audio signals in a deep portion of the second recording area using a magnetic head C1, and a second audio signal recording structure for subsequently recording a PCM audio signal to be recorded on a surface portion of the second recording area using a magnetic head D1. A magnetic recording and reproducing apparatus for recording first and second input video signals and first and second L and R channel input audio signals associated with first and second programs wherein the video signals are recorded on video signal recording tracks TA1 through TB2 formed on a magnetic tape T and, after a first audio signal to be recorded is recorded at a deep portion of an audio-exclusive track TC, a second recording audio signal is recorded on a surface portion thereof at a time interval using magnetic heads C1 and C2.
