Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は磁気ヘッドコアに関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a magnetic head core.
従来磁気ヘッド材料としてはフェライトが用いられてい

特性を十分に生かすことができなかった。Ferrite has conventionally been used as a material for magnetic heads, but as the coercive force of recording media increases, magnetic heads using materials with high saturation magnetic flux density are now in demand. Therefore, a magnetic head was devised in which a metal with high saturation magnetic flux density, such as sendust, was formed on ferrite. However, when manufacturing magnetic heads, a fusing process using lead glass is required.
It was confirmed that the sendust thin film was eroded by the lead glass during this fusion, and the characteristics of sendust, a high saturation magnetic flux density material, could not be fully utilized.

Therefore, an object of the present invention is to provide a magnetic head core that fully exhibits the characteristics of sendust formed on ferrite. “In a magnetic head core in which a sendust thin film is formed on the gap-forming surface of at least one of a pair of ferrite blocks constituting a magnetic circuit, sendust and gap material S10 are used.
．． It is characterized in that a Cr film is formed between the two.

OA form. In order to combine 1 and 1' to form a magnetic circuit, they are fused with lead glass 5 at 600° C.XIH, and the magnetic head core is completed by processing the track width and cutting. At this point, no corrosion by the lead glass of sendust was confirmed, and this magnetic head
, a magnetic head is completed by fusing glass to the slider of the slider and processing the hollow part.1 A magnetic head using the magnetic head core using the magnetic head core of the present invention is manufactured by fusing glass to the slider of the present invention. Compared to the conventional model without the 01 layer, both output and override values are approximately 30%

０Ｘ以上であればその効果が十分に発揮される。Therefore, by sandwiching the 01 layer between the sendust and the 810° angle as in this embodiment, it is possible to prevent the sendust from being corroded by the lead glass. Also, the thickness of the 01 layer is 30
If it is 0X or more, the effect will be fully exhibited.
