Claims (2)

2개의 회전헤드(4,5)를 헤드 스위칭 펄스에 의하여 절환하고, 자기테이프(1)의 경사트랙의 제 1 부분에 제 1 의 정보를, 또 제 2 부분에 제 2 의 정보를 기록 재생하는 자기기록 재생장치의 조정용 자기테이프에 있어서, 이 경사트랙의 이 제 1 부분에 이 제 1 의 정보를 제 1 의 레벨로 기록하고, 이 제 2 부분에 이 제 2 의 정보를 제 1 의 레벨과는 다른 제 2 의 레벨로 기록하는 것을 특징으로 하는자기테이프.The two rotary heads 4 and 5 are switched by head switching pulses, and the first information is recorded in the first part of the inclined track of the magnetic tape 1 and the second information is recorded and reproduced in the second part. In the magnetic tape for the adjustment of the magnetic recording and reproducing apparatus, the first information is recorded in this first portion of the inclined track at the first level, and the second information is recorded in the second portion with the first level. Magnetic tape recording at a second level. 2개의 회전헤드를 헤드 스위칭 펄스에 의하여 절환하고, 자기테이프의 경사트랙의 제 1 부분에 제 1 의 정보를, 또 제 2 부분에 제 2 의 정보를 기록 재생하는 자기기록 재생장치의 조정방법에 있어서, 이 경사트랙의 이 제 1 부분에 이 제 1 정보를 제 1 의 레벨로 기록하고, 이 제 2 부분에 이 제 2 정보를 이 제 1 의 레벨과는 다른 제 2 의 레벨로 기록한 자기테이프를 자기기록 재생장치로 재생하고, 재생신호의 RF 신호를 파형관찰수단으로 표시하고, 이 제 1 부분에 있어서의 이 재생신호에 이 제 1 의 정보의 RF 신호와 다른 레벨의 이 제 2 정보의 RF 신호가 나타나지 않도록, 이 회전헤드와 이 헤드 스위칭 펄스의 타이밍을 조정하는 것을 특징으로 하는 자기기록 재생장치의 조정방법.In the method of adjusting the magnetic recording / reproducing apparatus, the two rotating heads are switched by head switching pulses, and the first information is recorded on the first portion of the inclined track of the magnetic tape and the second information is recorded on the second portion. In this first part of the inclined track, the first information is recorded at a first level, and the second tape is recorded in this second part at a second level different from the first level. Is reproduced by the magnetic recording / reproducing apparatus, and the RF signal of the reproduction signal is displayed by the waveform observation means, and the reproduction signal in this first portion of the second information at a level different from the RF signal of this first information is displayed. And adjusting the timing of the rotating head and the head switching pulse so that the RF signal does not appear. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
