Abstract

PURPOSE:To efficiently perform the recording and reproduction of a digital signal with an image, by providing two kinds of read/write heads of a dedicated head which FM-modulates and records and reproduces a digital recording and reproducing dedicated head, and a video signal. CONSTITUTION:The video signal is recorded on an even-th track starting from the 0-th track on a recording medium 101, and the digital signal is recorded on an odd-th track on a first track group in a discoid floppy disk. The width of the 0-th track is wider than that of the first track, and a ratio between lengths T and W is set around in a proportion of three to two. A magnetic head consists of a vido signal recording and reproducing head core 103, and a digital signal recording and reproducing head core 105, and they are separated by a nonmagnetic material 104. The length of a video signal recording and reproducing head gap 106 is set as T, and that of a digital signal recording and reproducing head gap 107 is set as W, and a circuit part is completely separated by every signal.

とによるものである。The 0th trunk is somewhat wider than the 1st track. Video signals are recorded on even-numbered trunks including the 0th trunk, and digital signals are recorded on odd-numbered trunks that form the first track group. The relationship between length T and length W is preferably about 3:2. This is when you go off track.
This is due to the fact that the way the signal quality is affected by the deterioration of the S/N due to the reduction in the reproduced signal is different between video signals and digital signals.
