Abstract

PURPOSE:To form a magnetic recording head of which the thin magnetic film contacts always stably with a recording medium and which can maintain stably a recording density characteristic by providing a main magnetic pole made into the construction in which the thin magnetic film is sandwiched by holding materials softer than the hardness of said film and an auxiliary magnetic pole in a manner as to face each other with the recording medium in-between. CONSTITUTION:The magnetic recording head is constituted with the auxiliary magnetic pole 2 having a winding 1 and the main magnetic pole 6 with the medium 5 having an FeNi layer 3 and a CoCr layer 4 in-between. The medium 5 travels while the pole 6 and said medium 5 are held in contact with each other under specified load in order to execute magnetic recording and reproducing at high density. The pole 6 consists of the thin magnetic film 7 and the non-magnetic holding materials 8 for holding said film. The materials 8 are made of the material softer than the film 7. The top end of the pole 6 itself wears down gradully in such constitution but the materials 8 wear down earlier than the film 7 and therefore the film 7 is eventually exposed at all times from the top end of pole 6. The stable recording density characteristic is thus maintained.

Description

【発明の詳細な説明】 産業上の利用分野 本発明は垂直磁気記録を行うところの磁気記録ヘッドに
関するものでるる。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording head for perpendicular magnetic recording.

、一定の荷重で記録媒体に押しつけられた状態で媒体が
走行する。Conventional configuration and its problems Perpendicular magnetic recording is a technology that achieves high-density recording by recording in a direction perpendicular to the in-plane direction of the medium, but its basic head configuration is as follows: The recording medium is sandwiched between an auxiliary magnetic pole having a winding and a main magnetic pole. The media runs in the same state.

う状態が保たれず、記録密度特性が悪くなるという問題
がある。In a main pole having such a structure, it is common practice to use the hardest possible material for the holding material in order to prevent the main pole from being damaged by polishing. Therefore, when the tip of the main magnetic pole is run in contact with the medium under a constant load, it remains stable for a period of time such that the tip fits, but since the magnetic thin film is softer than the holding material, the tip of the magnetic thin film is held. There is a problem in that the magnetic thin film wears out before the material does, and as a result, the magnetic thin film cannot always be kept in stable contact with the medium, resulting in poor recording density characteristics.

発明の目的 本発明に以上の問題を解決し、磁性薄膜が、媒体に常に

磁気記録ヘッドを提供することを目的とするものでろ名
。OBJECTS OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and provide a magnetic recording head in which a magnetic thin film is always in stable contact with a medium and recording density characteristics can be maintained stably.

磁気記録ヘッドを提供するものである。Structure of the Invention The present invention achieves the above object, and includes a main magnetic pole and an auxiliary magnetic pole having a structure in which a magnetic thin film is sandwiched between a holding material whose hardness is softer than that of the magnetic thin film, and are provided so as to face each other with a recording medium in between. A magnetic recording head is provided.

ているが本実施例では、保持材８が磁性薄膜７よりも軟
らかい材料で構成されている。This embodiment consists of an auxiliary magnetic pole 2 having a winding 1, and a main magnetic pole 6 sandwiching a medium 6 having a FeN1 layer 3 and a QOCR layer 4. At this time, in order to perform high-density magnetic recording and reproducing, the medium runs with the main pole e and the medium 5ri in contact with a constant load. By the way, main magnetic pole 61/lj: magnetic thin film 7
In this embodiment, the holding material 8 is made of a softer material than the magnetic thin film 7.

とができるのである。In such a configuration, the tip of the main pole 6 itself gradually wears down, but the holding material 8 wears out earlier than the magnetic thin film 7, so the magnetic thin film 7 is always exposed at the tip of the main pole 6. As a result, stable recording density characteristics can be maintained.

きる。This embodiment shows the same structure as the previous embodiment except that the winding 1 is wound around the main magnetic pole 6@, and in this case also, the holding material 8 constituting the main magnetic pole 6 is made of a material that is softer than the magnetic thin film 7. The same effect as in the previous embodiment can be obtained by configuring it with a material.

なお本発明は前記実施例の構造に限らず、他の構造のヘ

録密度特性が得られるのでるる。As described in detail, the present invention is achieved by appropriately selecting a material whose hardness is softer for the holding material than the magnetic thin film of the main pole, so that the magnetic thin film can be kept in stable contact with the medium at all times, resulting in good recording. Density characteristics can be obtained.
