Helical scan type magnetic recording and reproducing apparatus |
摘要 |
<p>A helical scan type magnetic recording and reproducing apparatus of the present invention records/reproduces a video signal and a audio signal on/from tracks formed on a magnetic tape obliquely with respect to a longitudinal direction of a magnetic tape wound on a rotary drum. When a multiplexed signal containing a frequency modulated luminance signal and a low frequency converted chrominance signal and a frequency modulated audio signal which are related to an analog video signal are recorded/reproduced, the rotary drum is rotated in synchronism with a frame pulse of the analog video signal. When a digital video signal is recorded/reproduced, the rotary drum is rotated at a speed 1.25 times that when an analog video signal of the NTSC system is recorded/reproduced and at a speed 1.5 times that when an analog video signal of the PAL or SECAM system is recorded/reproduced. <IMAGE></p> |
