专利汇可以提供Magnetic recording device专利检索,专利查询,专利分析的服务。并且PURPOSE: To record a PCM audio signal without damaging a picture quality while the interchangeability with the magnetic recording and reproducing device of a conventional recording format is kept by supplying a second recording signal of a high frequency component to a magnetic head and recording the second recording signal to the surface layer of the magnetic layer of the magnetic tape in which a first recording signal is recorded.
CONSTITUTION: The device is equipped with magnetic heads CH3 and CH4 to scan recording tracks TA1, TB1, TA2, TB2... on a magnetic tape 1 in which the first recording signal VI is recorded and to have an azimuth angle different from the azimuth angle of magnetic heads CH1 and CH2 to record the first recording signal VI. The second recording signals SR3 and SR4 of the high frequency component are supplied to the magnetic heads CH3 and CH4, and the second recording signals SR3 and SR4 are recorded to the surface layer of the magnetic layer of the magnetic tape 1. Thus, the magnetic heads CH1 and CH2 to record the first recording signal are used and reproduction is executed, and then, the second recording signals SR3 and SR4 are not outputted, and reversely, when the magnetic heads CH3 and CH4 are used and reproduction is executed, the first recording signal VI is not outputted.
