AI Technical Summary

Problems solved by technology

[0015] However, there are many problems in the structure of setting the initial slit depth very deep, such as the limitation of the improvement of sensitivity, the control of high-density recording, and the limitation of high-density playback.
Also, does nothing to address tape life shortening
[0016] Also, it is impossible to realize the device for detecting the magnetoresistance effect type (or magnetic flux response type) MR head and GMR head having a structure in which the magnetic field varies with the recording medium by means of a very shallow gap by using the magnetoresistance effect. , this MR head and GMR head are mainly used in hard disk drives (HDD), and can also replace the magnetic head based on the above-mentioned magnetic induction principle, and be used in tape magnetic recording media

Abstract

A magnetic head wherein a flat head (FH1) is mounted on a rotary drum (DR1) on which a magnetic tape (MT) can be wound, the flat head (FH1) has a smooth flat face (PL1) opposed to the magnetic tape (MT) and subjected to fluid interference with the magnetic tape (MT), and a head element (HE1) in contact with the magnetic tape (MT) and subjected to magnetic interference therewith is disposed in the range where the magnetic tape (MT) is in contact with the smooth flat face (PL1).

Description

technical field [0001] The present invention relates to a magnetic head, a recording / reproducing method for a tape-shaped magnetic recording medium, and a rotary head mechanism. Background technique [0002] As a device for recording and / or reproducing signals on and / or from tape-shaped magnetic recording media, rotary drum type video cassette recorder devices are widely used, in which in order to pass In recording on a tape-shaped magnetic recording medium, tracks are formed at oblique angles, and playback is also performed by following such oblique tracks. In particular, in recent years, digital standard rotary drum type video cassette recorder devices have come into widespread use. [0003] As an example of a tape-shaped magnetic recording medium, a powder-coated magnetic tape is available. Its structure is such that needle-like or fine powder magnetic particles are coated on the plastic substrate to form a magnetic layer or magnetic surface thr...
