摘要：本发明涉及磁记录盘驱动器，其包括具有在同心数据磁道中取向在跨磁道方向上的磁化的盘。该同心数据磁道通过防护带彼此磁分隔开。感应写头使其写磁极和写间隙取向以产生跨磁道方向的磁场。该防护带通过含有沿磁道的磁化来提供磁分隔，在这种情况下，该写头还具有产生数据磁道旁边沿磁道方向上的磁场的擦除磁极和擦除间隙。磁致电阻读头使其自由层磁化方向垂直于盘表面且使其被钉扎层磁化方向平行于盘表面并正交于该自由层磁化方向。该读头可具有在跨磁道方向与它间隔开的侧边磁屏蔽件，从而防止来自相邻数据磁道的磁通到达该读头。

摘要： A magnetic head which enables the formation of a guard band on a magnetic recording medium, and which is particularly suitable for a magnetic disk, is disclosed together with a method of manufacturing thereof. The magnetic head is provided with a recording/reproducing head core (31) and an erasure head core (32) which is also used for forming a guard band, and which is integrally bonded in series to the head core (31). A magnetic circuit is constituted by magnetic metal members (34), (34'), (35), (35') formed on non-magnetic members (33), (33'). It is possible to record on a recording medium with a high coercive force and reduce the track width, and this magnetic head is highly accurate and easy to manufacture.

摘要： A magnetic head, such as a tape head, according to one embodiment includes an array of data writers for writing to multiple data tracks on a magnetic medium, a width of the array being defined between the data writers positioned farthest apart. An erase writer having a width at least about as wide as the width of the array is present for erasing at least part of the magnetic medium prior to the writing by the data writers. A plurality of readers may also be present. Preferably, the data writers and erase writer are formed on the same substrate.

摘要： A magnetic recording disk drive has a disk with the magnetizations in the concentric data tracks oriented in the cross-track direction. The concentric data tracks are magnetically separated from each other by guard bands. An inductive write head has its write poles and write gap oriented to generate magnetic fields in the cross-track direction. The guard bands may provide magnetic separation by containing along-the-track magnetizations, in which case the write head also has an erase pole and an erase gap to generate magnetic fields in an along-the-track direction on the sides of the data tracks. A magnetoresistive read head has its free-layer magnetization direction perpendicular to the disk surface and its pinned-layer magnetization direction parallel to the disk surface and orthogonal to the free-layer magnetization direction. The read head may have magnetic side shields spaced from it in the cross-track direction to prevent magnetic flux from adjacent data tracks from reaching the read head.

摘要： In a magnetic head comprising a read/write head and an erase head constructionally integrated with each other, the closed magnetic circuit of the erase head is arranged to be higher in magnetic reluctance than the closed magnetic circuit of the read/write head, whereby a magnetic flux to be drawn by the erase gap is reduced so as to prevent the leakage of the magnetic flux to the read/write head side.

摘要： A composite magnetic head having a recording/playback head and an erasing head combined in one unit through a nonmagnetic material is constructed such that at least one of two core halves constituting the erasing head adjacent to the recording and reproducing head is made of single crystal ferrite, a plane (100) of the single crystal ferrite is substantially parallel to a principal magnetic path-forming plane, and an angle .theta. between an orientation existing in the plane (100) and an operating gap (magnetic gap)-forming plane is in the range of 10.degree.-40.degree. or 80.degree.-120.degree.. The composite magnetic head thus constructed can be made to have a reduced distance between magnetic gaps of both heads so as to be suited for being attached to the compact high-density recording and reproducing apparatus while eliminating crosstalk.
