    摘要： An information storage apparatus comprises a one or more storage media (168), which include a plurality of information tracks. Each storage medium (168) has a head assembly (170) having a substantially planar surface and a plurality of read/write heads positioned in registry with said information tracks. The read/write heads are arranged substantially in the plane of the planar surface. The information storage medium (168) and the head assembly (170) are arranged in mutually sliding abutment such that the read/write heads are substantially in sliding contact with the outer surface of the information storage medium in use.
    In another aspect an information storage and retrieval apparatus comprises an information storage medium (168) comprising an information storage area, and an array (170) of information read and/or write heads. The information storage medium (168) and array of heads (170) are arranged to be oscillated with respect to each other in use such that each region of the information storage area is aligned with at least one of the read/write heads during the oscillation.

    摘要： A thin film magnetic recording head (46) is provided with a tape bearing surface that has magnetically isolated channels while still providing a maximum continuous surface area with which to engage the media. This can be accomplished by providing spaces (50,455,460) in the magnetically permeable thin film (34,450) that are large enough to prevent cross-talk between the channels, but small enough to prevent significant interference with the moving media. Alternatively, magnetically impermeable thin film spacers (50,455,460) can be provided to magnetically isolate each of the channels. The spacers are generally even with the magnetically permeable thin film so as to provide a continuous media-bearing surface.

    摘要： A multiple channel magnetic tape head assembly (10) defines a plurality of spaced-apart transducer elements (24, 26) along an integral bar (12) of ferromagnetic material. Each element (24, 26) formed by grinding operations performed upon the integral bar (12), has a magnetic gap (28) and flux circuit which is isolated from cross-talk with the other elements. Each element is precisely located by the integral bar (12), portions of which remain after griding. The head assembly provides an aligned longitudinal tape wear region and may further provide widened transverse wear regions adjacent to each of the transducer elements. A fabrication method for forming a multiple channel magnetic tape head assembly is also described.

    摘要： A method of producing a magnetic head comprising the steps of forming a track width restricting groove on each of a pair of head core blocks (91); fusion joining the head core blocks (91) to each other with glass while the head core blocks (91) are positioned with the track width resticting grooves aligned with each other; forming, on at least one of a pair of faces of the head core blocks (91) remote from joining faces at which the head core blocks (91) are joined to each other, a groove at an angle substantially equal to an azimuth angle of a magnetic gap of a magnetic head to be produced; and cutting the head core blocks (91) in a direction substantially perpendicular to a bottom face of the groove to form a head chip.

A multi-channel magnetic head is also disclosed which includes a plurality of magnetic heads having different azimuth angles of the magnetic gaps, wherein each magnetic head is formed by abutting a pair of magnetic core halves to each other, each of the magnetic core halves having a magnetic metal film formed in the vicinity of at least a substrate surface facing a magnetic recording medium, for defining a magnetic gap between the magnetic metal films, and wherein a recess for forming a coil is formed in the abutting surface of at least one of the magnetic core halves, and the coil is formed in the recess by thin film forming technique. The methods for producing the magnetic head and the multi-channel magnetic head are also disclosed.
