Abstract: There is provided a magnetic head for perpendicular magnetic recording which has a main pole core (15, 20, 20') and an auxiliary pole core (16, 23, 23') and is constituted such that the side surface of the auxiliary pole core opposite to the main pole core near the surface side which faces a magnetic recording medium (10) is formed like a concave or convex shape with respect to the main pole core. This magnetic head has excellent recording and reproducing characteristics which are not subjected to the interference actions on the recording and reproduction due to the edge portion of the auxiliary pole core.

Abstract: A process for collectively obtaining the profile on magnetic heads during their manufacture consists in machining the active faces of the magnetic heads using an abrasive ribbon to confer on them a rounded profile corresponding to the desired profile. The process comprises two steps. In the first step, the chamfers (45) which delimit said rounded profile are produced on the active faces. In the second step, the active faces are machined using said abrasive ribbon (50) and means of mechanical deformation (51) which act on the adhesive ribbon and press it against the active faces so as to obtain the desired profile. Application to the manufacture of magnetic heads, in particular for video cameras.

Abstract: To obtain the correct tape wrap angle (124) at the head in a cassette loaded recorder, tape guiding support "outriggers" (117, 119) integral with the head assembly (113) are provided. The outriggers (117, 119) are located on either side of the active magnetic transducing element (121) of the head structure to guide the tape (116) and to establish the tape/head wrap angle (124) independent of the exact locations of the cassette guides (114, 118). Slots (129, 131) separate the magnetic transducing element (121) from each of the outriggers (117, 119), presenting an edge (126, 128) at each side of the head to skive any air film adherent to the moving tape (116) as it approaches the head's transducer (121). Additionally, the entire head and outrigger structure (113) is fabricated from the same or mechanically similar materials and has an overall constant area profile contour which wears at a uniform rate due to tape abrasion.

Abstract: Magnetic transducer-keeper (28) combination embodiments of the invention. Each has a magnetic core (20) defining a physical gap (26) and a thin magnetic keeper (28) arranged in close proximity of the core (20) to bridge the gap (26). A magnetic flux (48) from the gap (26) saturates the keeper (28) in an area bridging the gap (26) thereby forming a signal transducing zone (50) in the keeper (28). The keeper (28) is maintained stationary and the core (20) moved or scanned with respect to the same, thereby moving or scanning the transducing zone (50) in the keeper (28).

Abstract: Magnetic head comprising a main element (2) formed in a thin-film technique, with at least a transducing element (5) and a sub-element (4) arranged against the main element. An adhesive (21) is present between a face of the main element facing the sub-element and a face of the sub-element facing the main element. A thin but strong adhesive layer is obtained by providing at least one of said faces with a structure of parts which are either re-entrant or projecting with respect to the relevant face so that the adhesive is present both on and between said parts.

Abstract: An information storage system having a ring head (220) sliding on a rigid magnetic storage disk in such close proximity that the magnetic field felt by the media layer or layers of the disk has a larger perpendicular than longitudinal component so that data is stored in a perpendicular mode. The head to media separation during writing of data to the media is a small fraction of the amagnetic gap (160) separating the poletips (155, 157) of the head. Reading of data may be inductive or may be via a magnetoresistive sensor (222) which is coupled to the magnetically permeable core of the ring head far from the poletips. The media preferably has a high perpendicular anisotropy.

Abstract: The invention provides a new lapping sensor configuration to aid in the fabrication of very small sliders. The breakpoint (34) and resistive portions (32) of an electrical lapping guide (30) may be separated and positioned on separate slider sites or may be positioned adjacent to slider sites. In addition, a lapping sensor (30) may be positioned on one rail (14) of a slider which consists of two rails (12, 14), the other rail (12) having a recording head (20). The invention also positions a lapping sensor having both the resistive (32) and breakpoint (34) portions of an electrical lapping guide between adjacent slider sites.
