摘要： 0 In a magnetic information storage device of the type having a slider which moves relative to a magnetic recording medium such as a disk, the slider has a non-rectangularly shaped air bearing surface that provides the slider with a high degree of stability. The non-rectangular shape is preferably either a triangle or a trapezium. The non-rectangularly shaped slider includes a tapered leading edge and a flat vertical surface as its trailing edge. A conventional thin film head element can be deposited on the vertical surface, if the slider is fabricated from ceramic material, or a conventional head element having a wound coil can be disposed on the vertical surface, if the slider is fabricated from ferrite material.

摘要： A suspension assembly for a magnetic transducer head 150V includes a normally flat gimbal spring 308 in the form of a figure eight, with a pair of tabs or ears 308G at the sides of the eight by means of which the spring is mounted in a support arm 104V. A backup spring, 310 has legs 310D and 310E extending from a mounting side of a hole in the arm 104V towards the other side. Legs 310F and 310G extend back again and connect to a depending leg 310H and flange portion 3101 effective to provide pressure on the middle of the gimbal spring 308. The backup spring 310 provides resilient backup force against translation of the transducer head on its main axis and the gimbal spring 308 provides resilience against transducer pitching and rolling.

摘要： An assembly is composed of a transducer (33), an actuator arm (34), an inflatable envelope (30) including two flat surface portions, one of which surface portions is secured to the actuator arm and on the other of which surface portions is mounted the transducer, means (72) for inflating the envelope so as to move the transducer into an operating position and for deflating the envelope so as to return the transducer to a rest position, and reinforcements (40,42,56), associated with the parts of the envelope between the flat surface portions, for maintaining the flat surface portions substantially parallel to each other when the envelope is inflated. The envelope (30) is formed from a flexible non-elastic material, and the reinforcements (40,42,56), both constantly maintain the flat surface portions substantially parallel to each other and constantly maintain the parts of the envelope between the flat surface portions substantially parallel to each other.

摘要： A slider for flying a magnetic head on a fluid bearing above moving magnetic recording media is disclosed in which a fluid bearing surface includes a generally planar fluid support surface extending generally transverse to the direction of movement of the media, a ramped leading edge and a cavity having a generally spherical surface formed in the fluid support surface and spaced from the leading edge thereof. A method of making such a slider is also disciosed.

摘要： A semi self-loading air bearing ferrite slider assembly has a tapered leading surface portion (18) extending from a cross rail (15) from which side rails (13, 14) and a middle rail (16) extend rearwardly. The middle rail (16) progressively narrows to form the transducer portion (37) where it extends across the gap (35) between the body portion (10) and core piece (29) near the trailing end of the rail. Etched surfaces (21, 22) between the middle rail (16) and the side rails (13, 14) provide subambient pressure during operation when the slider is in flight whereby the balance between the repelling air bearing surface (11) and attraction of the subambient pressure areas (21, 22) supplements the stabilizing force of the load arm.

摘要： A magnetic head assembly includes a ferrite core (10) sandwiched between two ceramic layers (12, 14). Alumina films (11, 13, 15, 17) are deposited by sputtering on the sides of the ferrite core and on the ceramic layers in one embodiment, and on the ferrite core only in another embodiment, which are then bonded to form an integral head assembly. Slots (20, 22, 24, 26) to provide flying height control are formed in the air bearing surface of the ceramic layers. The process of making the assembly includes the steps of sputter etching the ferrite and ceramic prior to the deposition of the alumina.

摘要： In a magnetic disk apparatus according to the present invention, a slider has a sliding surface (K) and a reflecting surface (M). The height of the reflecting surface (M) from the magnetic disk (1) is greater than that of the sliding surface (K) from the disk (1), when the slider (6) flys above the disk (1), so that there exists a minute difference in level between the sliding surface (K) and the reflecting surface (M). The flying height of the sliding surface (K) of the slider (6) from the magnetic disk is measured. When the magnetic disk (1) is rotated, the slider (6) flys from the disk (1). In this state, reference flying height, i.e., the flying height of the reflecting surface (M) from the magnetic disk (1) is measured by the optical interference process. Then, the minute difference is subtracted from the measured reference flying height to obtain the flying height of the sliding surface (K) of the slider (6) from the magnetic disk (1). According to the invention, even if the minimum flying height of the sliding surface (K) of the slider (6) is shorter than 0.1 micrometer, the measurement can be effected by the optical interference process. In general, moreover, a minute flying height between a fixed datum plane and an object flying above the datum plane can be measured accurately.

摘要： The start-up of a rotating disk file is controlled by first moving the sliders (30, 32, 40, 42) supporting the read/write leads radially outwards from the inside diameter (20) of the disks (10, 12, 14) by applying a voltage from voltage source (70) to voice coil motors (34, 44), sensing the position of the sliders (30, 32, 40, 42) on the disk surfaces with a position sensor (80), initiating rotation of the disk drive motor (18) when the sliders (30, 32, 40, 42) have moved a dewetting distance, and terminating radial translation of the sliders (30, 32, 40, 42) when the disk drive motor (18) has reached operating speed and the sliders (30, 32, 40, 42) are riding on air bearings above the disks. The instrumented radial translation of the sliders (30, 32, 40, 42) overcomes the stiction forces at the slider-disk interface without damage to the read/write heads, the disks (10, 12, 14) or the slider suspensions (36, 38, 46, 48).
