Magnetic recording and reproducing device
专利汇可以提供Magnetic recording and reproducing device专利检索，专利查询，专利分析的服务。并且PURPOSE: To reproduce a signal by a high definition device and a low definition device by sectioning a track of a magnetic tape into 4 fields, recording a digital signal while an analog signal is sampled by frequencies (f) and 2f to one of the fields in a prescribed relation.
CONSTITUTION: An oblique track is formed by a rotary magnetic head in the lengthwise direction of a magnetic tape. One track having a winding angle of 221° is sectioned into 4 fields AWD by 54°. Stereo audio signals L, R are sampled by a frequency (f) and digitized to record an odd number L signal and an even number R signal in the field A and to record an odd number R signal and an even number L signal to the next rack field adjacent to the former track. The signals L, R are sampled by frequency 2f, a new odd number L odd number R signal and the even number L signal are recorded to a field A adjacent to the former field. Thus, the signal is reproduced by a high definition device and the low definition device.
