Abstract

PURPOSE:To attain vertical magnetic recording easily and surely, by providing a thin piece of ferromagnetic substance at the back of a magnetic recording medium located between reels, and opposing the end to the surface of said medium, and facing the recording side to one side of said substance. CONSTITUTION:In selecting the recording mode, an auxiliary magnetic pole 8 is shifted in front, i.e., toward magnetic tape 3 accompanied with the movement of a head base and contacted. When a signal current flows to a coil of the pole 8 in this state, a magnetic flux corresponding to the recorded information is generated at the tip of the magnetic pole 8. The magnetic flux thus generated passes through a magnetic tape 3 and is collected to the ferromagnetic substance thin piece 6 of a main magnetic pole 5 provided at the back side. In this case, since a magnetic substance layer 3b is located to the main magnetic pole 5, the magnetic flux collected with the piece 6 passes through the magnetic substance layer 3b, allowing to attain the vertical recording using the width of the piece 6 as the unit.

長時間記録が達成されるものである。In recent years, with the rapid development of electronic technology, there has been a tendency for recording sound fk on magnetic recording media to increase. A perpendicular magnetic recording system has been proposed as a method for increasing the total recording density. This perpendicular magnetic recording method uses magnetization perpendicular to the surface of the magnetic recording medium to record, whereas conventional magnetic recording uses magnetization along the in-plane direction of the magnetic recording medium. It is something. In such a perpendicular magnetic recording system, since the magnetization pinch is narrowed, high-density recording is easily achieved, and long-time recording is thereby achieved.

この場合、その取り扱いが容易々テープカセットケ用い
て垂直磁気記録を行なおうとすると。In this case, if you try to perform perpendicular magnetic recording using a tape cassette, which is easy to handle.

K, which can effectively generate magnetic flux perpendicular to the magnetic tape surface, can be applied to the entire magnetic tape by the magnetic head (auxiliary magnetic pole) and the main magnetic pole, which generate magnetic flux corresponding to recorded information. I want it, I want it. [7 However,
Unlike conventional tape cassettes, effective perpendicular magnetic recording could not be performed with a cassette case that contained only a magnetic tape.
