发明名称 DIGITAL VIDEO SIGNAL RECORDING APPARATUS
摘要 PATENT 390100.2619 A digital video tape recorder includes a rotary drum that has a leading head and a trailing head mounted thereon for recording video signals in respective slant tracks scanned on the tape while the tape is advanced. Each of the tracks includes, in sequence in the scanning direction of the respective head, a first auxiliary recording area, a second auxiliary recording area and a video signal recording area. The heads are displaced with respect to each other on the drum in the scanning direction by a distance that is less than the distance in the scanning direction between an ending edge of the first auxiliary recording area of the track formed by the trailing head and a starting edge of the video recording area of the track formed by the leading head. Because of the arrangement of the heads, after-recording of audio signals in the first auxiliary recording area by the trailing head is completed before the leading head begins reproduction of video signals. This prevents cross-talk from the audio recording signal that would disrupt the reproduced video signal. A satisfactory picture can therefore be reproduced during afterrecording of audio signals. i
