Abstract

PURPOSE:To increase a data transfer speed by providing plural recording bands on a magnetic tape, recording simultaneously information in this recording band, or reproducing simultaneously the information recorded on the magnetic tape. CONSTITUTION:A cylinder 11 is rotated in the cylinder rotating direction, and with respect to a magnetic tape 15, recording and reproducing are executed. One recording band 25 is constituted to tracks 22a-22d which have been recorded by a magnetic head 14a onto the tape 15. In the same way, one recording band 26, and one recording band 27 are formed by tracks 23a-23d which have been recorded by a head 14b, and by tracks 24a-24d which have been recorded by a head 14c, respectively. In this case, not only the heads 14a-14c but also one magnetic head whose azimuth angle is different are placed at suitable position of a cylinder outside peripheral part 13. In this way, it becomes possible to make an angle of a magnetic pattern different between adjacent tracks, and guard bandless high density recording can be realized.

ものがある。On the other hand, the development of digital video tape recorders that digitize video signals for recording and playback is currently underway.
It is necessary to increase the speed to 00 Mbps. Furthermore, there is a strong demand for higher data transfer speeds for magnetic recording and reproducing devices used as external storage devices for computers.

磁気テープの相対速度を高める方法があった。In order to increase data transfer speeds, conventional rotary head systems have two methods: (1) increasing the rotational speed of the cylinder, and (2) increasing the cylinder diameter to improve the relative relationship between the magnetic head and magnetic tape. There was a way to speed it up.

る欠点があった。Problems to be Solved by the Invention However, when the relative speed between the magnetic head and the magnetic tape is significantly increased, the magnetic tape does not come into complete contact with the magnetic head, and in addition, when the cylinder rotation speed is increased, the bearing part wears out. This has the disadvantage that the motor speed becomes extremely large and the motor rotation speed needs to be increased, which significantly shortens the life of the equipment.
