[Claims]
1. A multi-magnetic head that slides relative to a magnetic recording medium having a plurality of tracks to magnetically record and / or reproduce information.
With multiple magnetic cores with magnetic gaps and coiled windings,
A plurality of magnetic shield plates that perform magnetic shielding between the plurality of magnetic cores,
A support member made of a non-magnetic material in which the plurality of magnetic cores and magnetic shield plates are alternately arranged at predetermined intervals in the track width direction to support the sliding surfaces of the magnetic recording media in an exposed state.
A magnetic shield case having an opening for exposing at least the magnetic recording medium sliding surfaces of the plurality of magnetic cores and surrounding the plurality of magnetic cores, a magnetic shield plate, and a support member to perform magnetic shielding.
A head case having an opening on the sliding surface side of the magnetic recording medium and accommodating the plurality of magnetic cores, a magnetic shield plate, a support member, and a magnetic shield case.
A multi-magnetic head characterized by having.
2. The multi-magnetic head according to claim 1, wherein the magnetic shield case is formed so as to cover at least a part of the support member on the sliding surface side of the magnetic recording medium.

【発明の属する技術分野】
本発明は、磁気記録媒体に対して相対的に摺動して情報の磁気記録または/及び再生を行う磁気ヘッドに関し、特に複数のトラックを有した磁気記録媒体に対して情報の磁気記録または/及び再生を行うマルチ磁気ヘッドに関するものである。
[0001]
[Technical field to which the invention belongs]
The present invention relates to a magnetic recording medium with respect to slide relative relates to a magnetic head for magnetic recording and / or reproducing information, the magnetic recording medium to the information of the magnetic recording or that particular a plurality of tracks / And the multi-magnetic head that performs reproduction.

そこで本発明の課題は、上記のカードリーダ用のヘッドに限らず、複数のトラックを有した磁気記録媒体に対して情報の磁気記録または/及び再生を行うマルチ磁気ヘッドにおいて、その2つを記録用及び再生用として接近して配置して同時に記録再生を行った場合、記録用のヘッドから漏れた磁束が再生用のヘッドに侵入してノイズとなる、いわゆる磁気的なクロスフィードを低減し、再生を正確に行える構成を提供することにある。 Therefore, the subject of the present invention is not limited to the above-mentioned head for a card reader, but a multi-magnetic head that magnetically records and / or reproduces information on a magnetic recording medium having a plurality of tracks can record the two. When recording and playback are performed at the same time by arranging them close to each other for use and playback, the magnetic flux leaking from the recording head invades the playback head and causes noise, so-called magnetic cross feed is reduced. The purpose is to provide a configuration capable of accurate reproduction.
