Abstract:
A negative pressure air bearing slider (20) which exhibits reduced flying height sensitivity with respect to changes in ambient pressure, e.g., altitude changes. The slider (20) has a shallow cavity (10) within a negative pressure cavity region. The net downforce arising from the negative pressure region of the selected air bearing planform may be controlled or reduced by providing a deeper subcavity (22) within the negative pressure cavity region.
Abstract:
To provide an economical magnetic head assembly of the type in which a magnetic head slider and a suspension are connected by conductive wires in such a manner as to absorb extension and contraction, a work (50) is constituted from a magnetic head slider (11) equipped with a connection terminal circuit pattern (15), and a suspension (14) equipped with a wiring pattern (31) and a connection terminal circuit pattern (41). Both connection terminal circuit patterns are connected by wire bonding and flexible portions A and B are disposed at a part of the suspension (14) so that the wirings (43) between both connection terminal circuit patterns (15 and 41) absorb extension and contraction of the wirings (43).
Abstract:
A floating magnetic head comprises a head core (1) including core halves (1A and 1B) having magnetic films (14) and joined with a gap spacer (41) in between, and a dummy plate (3) stuck to one side face of the head core (1) parallel to the magnetic films (14). The assembly of the core (1) and dummy plate (3) is attached, at its end perpendicular to the magnetic films (14), to a housing (2). Since the core halves (1A and 1B) composed of C- or I-cores do not protrude from the magnetic head (5), the floating of the magnetic head (5) is not affected and, therefore, it is not required to form the housing (2) or an ABS surface (4) in a special shape.
Abstract:
This invention relates to a technology of a floating magnetic head used for a magnetic disk apparatus. A laminated head core (1) and a dummy plate (3) bonded to the head core (1) through a bonding glass layer (m) are integrally bonded to one of the side surfaces of a housing (2) having a substantially cubic body through the bonding glass layer (m), and constitute a slider (5) equipped with the head core. This slider (5) equipped with the head core is connected to an actuator of the magnetic disk apparatus main body through a leaf spring support mechanism and constitutes a floating magnetic head. Accordingly, in this floating magnetic head, a C core or an I core does not protrude out from the magnetic head and for this reason, no adverse influences are imparted on floating of the magnetic head. Further, inductance of winding can be reduced, high frequency characteristics are excellent, and handling property is also excellent.
Abstract:
A slider body (10) supporting magnetic transducer elements (14) for use in a magnetic recording system with a disk (20) includes at least one primary load-bearing surface (12) which is covered with a film having anti-frictional, self-lubricating properties. The film is composed of an immobile (e.g. solid) lubricant material. Processes for forming the solid lubricant layer on the load-bearing surface (12) of the slider body (10) include heat bonding or vapor phase deposition.
Abstract:
A flying head slider (10') is flown above a rigid rotating magnetic disk (37) at such a height that it is both aerodynamically stable and immune to collisions with disk asperities (36). A position adjustable magnetic transducer (2') is mounted on the slider (10') and is controllably lowered to an operating position very close to the disk where its position is maintained by a servo system. An anticipator probe (25') detects the presence of asperities (36) on the disk in the path traversed by the transducer (2'), and generates a control signal which causes the transducer to be retracted to a safe height.
Abstract:
A disc drive (10) having an actuator arm (16) to support a slider (24) carrying a transducing head (56) adjacent a selected data track (34) of a disc (30) having a plurality of concentric data tracks (34) includes a microactuator (54) on a leading edge surface (60) of the slider (24) to effect fine positioning of the transducing head (56) with respect to the selected track (34). The microactuator (54) includes a spatial region (63, 65) on the leading edge surface (60) of the slider (24). A microactuator element (72, 74, 92, 94, 142, 172) spans the spatial region (63, 65) and is responsive to a voltage to selectively expand and contract, thereby bending to alter the position of the slider (24) and the transducing head (56).
Abstract:
A slider (36) supports a transducer (44) proximate to a lubricated recording medium (16). The slider (36) includes a slider body, a raised rail (38, 40) formed on the slider body and a fluid flow pattern across the slider body which has at least one stagnant flow region (70, 72, 74, 76). A surface discontinuity (80, 82, 84, 86, 92, 102, 110, 112, 114, 116, 122, 130, 138) is formed on the slider body and is positioned within the stagnant flow region (70, 72, 74, 76) to inhibit lubrication (78, 79) collected within the stagnant flow region (70, 72, 74, 76) from migrating to the raised rail (38, 40).
