本発明は、磁気記録媒体に信号の記録再生を行なう装置
の磁気ヘッド機構に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic head mechanism for an apparatus for recording and reproducing signals on a magnetic recording medium.
磁気シートにフレーム信号の記録を行なう場合＊ ５
１ＳＯＯｒｐｍで磁気シートを回転させておき。When recording frame signals on a magnetic sheet*5
Rotate the magnetic sheet at 1SOOrpm.
２つの磁気ヘッドを用いて、それぞれフィールド信号を
記録する方式のものが知られている。A method is known in which two magnetic heads are used to respectively record field signals.
このとき、磁気シートの利用率を高めるため。At this time, to increase the utilization rate of the magnetic sheet.
また、磁気ヘッド移動機構を簡単にするため。Also, to simplify the magnetic head movement mechanism.
通常２つの磁気ヘッド相互の間隔を、磁気シート利用幅
の１／２に設定する。例えば磁気シートの記録可能な最
内周半径を１５１．最外周半径を２５ｍｍとした場合は
、２つの磁気ヘッド間隔を（２５−１５）／２＝４■に
設定する。Usually, the distance between two magnetic heads is set to 1/2 of the width of the magnetic sheet. For example, the recordable innermost radius of a magnetic sheet is 151. When the outermost radius is 25 mm, the interval between the two magnetic heads is set to (25-15)/2=4.
ガートバンドを含めた１トラツクの巾を８０μｍとすれ
ば、磁気シートには８ ｖｍ／ ｓμｍ＝１００トラッ
クのフィールド信号が記録できる。また、磁気ヘッド間
隔が４−であるから、その間には１度５０トラツクのフ
ィールド信号が記録される。If the width of one track including the guard band is 80 μm, field signals of 8 vm/s μm=100 tracks can be recorded on the magnetic sheet. Further, since the magnetic head spacing is 4-, field signals of 50 tracks are recorded at one time in the spacing.
２つのヘッドを使用し、フレーム信号の記録再生を行な
う場合は、５０トラック−５０フレームの信号を取扱う
ことができる。When two heads are used to record and reproduce frame signals, signals of 50 tracks and 50 frames can be handled.
さて、２つの磁気ヘッドを上記した゛手段によって設置

4 is the magnetic head support wind.
５は案内板であり、磁気シート２をなめらかに回転させ
ている。A guide plate 5 rotates the magnetic sheet 2 smoothly.
この従来の機構では第１図から明らかなように、磁気へ
ラドチップ３ａが並列に２個設けられているため、磁気
シート２との接触状態が良好でなく、ａ１気シート２が
逃げた状態になり、スペースロスが増し、良好な記録、
再生特性を得ることができない。As is clear from FIG. 1, in this conventional mechanism, since two magnetic held tips 3a are provided in parallel, the contact with the magnetic sheet 2 is not good, and the a1 air sheet 2 escapes. , space loss increases, good record,
Unable to obtain regeneration characteristics.
本発明の目的は上記従来技術の欠点をなくｌ−１磁気ヘ
ツドと磁気シートの接触状態が良好に保てるようにした
磁気ヘッド機構を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic head mechanism that eliminates the drawbacks of the prior art described above and can maintain good contact between the 1-1 magnetic head and the magnetic sheet.
本発明では、２つの磁気ヘッドの間に、磁気シート面圧
向かって突出材を設け、突出材と磁気シートの間を移動
する空気流により、磁気シートに加わる大気圧を低減し
、磁気シートを磁気ヘッド側へ吸い寄せ、磁気シートと
磁気・＼７ドの接続状態を良好にする。In the present invention, a protruding member is provided between two magnetic heads toward the surface pressure of the magnetic sheet, and an air flow that moves between the protruding member and the magnetic sheet reduces the atmospheric pressure applied to the magnetic sheet. Attracts it to the magnetic head side and improves the connection between the magnetic sheet and the magnetic field.

と、突出材６と磁気シート２間に空気流が生じ、突出材
６側に磁気シート２が吸着される。このようにすれば。An embodiment of the present invention will be described below with reference to FIG. 1st
As in the figure, 1 is a motor, 2 is a magnetic sheet, 3 is a magnetic head, 6α is a Herad chip, 5b is a head winding, 4 is a magnetic head support, and 5 is a guide plate. 6 is a protruding member provided according to the present invention. The magnetic sheet 2 is rotated at a constant rate by the motor 1. The magnetic sheet 2 rotates smoothly along the guide plate 5, but since the airflow is disturbed in the part facing the magnetic head 3, the magnetic sheet 2 rotates smoothly along the guide plate 5.
I start running away from it. However, when the protruding member 6 is provided, an air flow is generated between the protruding member 6 and the magnetic sheet 2, and the magnetic sheet 2 is attracted to the protruding member 6 side. If you do it like this.
磁気シートと２つの磁気ヘッドの接触状態を適正に保た
