摘要： Disclosed is a slider with an air bearing surface for flying a magnetic transducer on an air lubrication film over a moving recording medium. The air bearing surface allows the slider to fly at a close and substantially uniform height over the disk surface regardless of the skew angle of the air flow. The slider has a pair of nonidentical, nonsymmetrical rails disposed about the longitudinal axis of the slider, which through the viscous effects of the air flow, provide the air lubrication film when the recording medium is in motion.

摘要： A magnetic recording head for longitudinal rigid-disk recording is described. The recording head is characterized by an I-bar shaped magnetic core (32) which is attached flushly along the side (39) of a slider body (31). The core has a pole body section around which a wire coil (56) is wrapped for inducing magnetic flux changes in the media during write operations and for sensing magnetic flux which emanates from the disk surface during readback operations.

摘要： The air bearing surface (ABS) of a head slider is formed with configured rails (48, 50, 58) and leading edge tapers (40, 42). In implementations of the invention, two side rails (48, 50) extend only partially from leading edge tapers to the slider trailing edge. The inner edges of each side rail (48, 50) are formed with at least two opposing angles so that at least two rail sections vary in width along the length of the rail. Each side rail (48, 50) is shaped with an oblique angle to reduce the rail width and a reverse angle to form the sections of differing widths. The leading edge side tapers may be angled for control of pitch stiffness of the slider. In one embodiment of the invention, a third center rail (58) extends from a center taper (56) to the slider trailing edge where the transducer (61) is located. In another embodiment, a short center pad is provided at the trailing edge. In an alternative design, only two side rails are used without a center rail or pad. The ABS geometries disclosed herein include angled rail sections that provide controlled pitch and constant flying height during transducing operation in a disk drive.

摘要： A magnetic transducer and suspension assembly suitable for use in both contact recording and in winchester-type applications is described. A generally rectangular elongated flat suspension member includes a vertical-type inductive read/write transducer formed integrally with the suspension member and is embedded in one end of the suspension member. The vertical inductive transducer is suitable for vertical recording applications. The transducer vertical magnetic pole tip and magnetic yoke structure are formed at one end of the suspension member with the vertical pole tip extending to and exposed at an air bearing surface formed on the lower surface of a slider-shaped protrusion extending from the lower surface of the end of the suspension member. The integral transducer/suspension assembly can be adapted for either flying above the recording media or for use in continuous contact with the recording media. The air bearing surface is formed on the lower surface of a wear pad. The fabrication of the transducer/suspension assembly is adapted to be performed at the wafer level.

摘要： The fly height of read/write heads in multiple disk drives is dynamically adjusted to optimum fly height by a servo loop. The fly height is sensed in real time with a harmonic ratio fly height detector and compared to an optimum or reference fly height. The suspension system of each head is adjusted in accordance with the departure of the fly height of that head from the optimum fly height. The adjustment of the suspension system is accomplished by bonding a piezoelectric film to the flexible suspension arm carrying each head. The fly height is corrected for both radial and circumferential error as the head changes radial and circumferential position relative to the disk surface. The reference fly height, to which each head is moved by the servo loop, may be selectively changed in the fly height servo operation. This can be done to lift the heads away from the disk surface during track seek mode or disk drive sleep mode. The reference fly height can also be changed to lower the heads towards the disk surface during error recovery mode.
摘要翻译： 多个磁盘驱动器中读/写磁头的飞行高度通过伺服回路动态调整到最佳飞行高度。 使用谐波比飞行高度检测器实时感测飞行高度，并与最佳或参考飞行高度进行比较。 每个头部的悬挂系统根据该头部的飞行高度从最佳飞行高度的偏离来调节。 悬挂系统的调整是通过将压电膜粘合到携带每个头部的柔性悬挂臂来实现的。 当头部相对于盘表面改变径向和周向位置时，对于径向和周向误差来校正飞行高度。 可以在飞行高度伺服操作中选择性地改变每个头部被伺服回路移动的参考飞行高度。 这可以在磁道寻道模式或磁盘驱动器睡眠模式下将磁头抬离磁盘表面。 也可以改变参考飞行高度，以便在错误恢复模式期间将磁头降低到磁盘表面。

摘要： It is an object of the invention to realize a DTF control in a wide frequency range and a noiseless high-speed replay at several tens of times the normal relay speed without degradation of picture quality. It is also an object to provide an optimum contact between the head and the tape at all times by performing the tension control with high precision and in wide frequency range. A pair of supply side stationary pins 10a ₁ , 10a ₂ and a supply side movable pin 9a driven by a supply side tape actuator 11a are provided on the magnetic tape supply side of the head cylinder that has a rotary head H . By controlling the supply side tape actuator 11a to move the movable pin 9a , the tension of the magnetic tape T at the head cylinder can be controlled. When the tape is replayed at speed different from the recording speed, the supply side tape actuator 11a and a takeup side tape actuator are operated differentially from each other to perform a good tracking.

摘要： A magnetic head-to-media backer device (1) comprising an elastically deformable reed-like backer member (3) adapted to urge a flexible magnetic media (5) into contact with a magnetic head (7), is characterized in that a rigid frame (9) has a cavity (11) defined at least by a pair of opposite walls (13, 15) shaped to hold the backer member bent in an arc with two opposite leg portions (17, 19) of the backer member captured within the cavity to permit them to be deformed against respective ones of the opposite walls and a center portion (21) of the backer member protruding from an opening (23) to the cavity to permit it to be depressed at least part way into the opening to deform the leg portions toward the opposite walls. Thus, when a magnetic head (7) is forced against the center portion the center portion (21) can be depressed into the opening (23) until the leg portions (17, 19) are deformed against the opposite walls (13, 15), thereby providing a very stable support for the magnetic head.

摘要： A pair of oppositely-disposed stabilizer devices (18, 18') support opposed magnetic heads (24, 24') for interfacing with opposite sides of a rotating magnetic disk (6). Each stabilizer device includes a block (20, 20') with an opening (22, 22') through which the magnetic head protrudes for engagement with a respective side of the disk. An air bearing surface (26, 26') on each block surrounds the opening adjacent the disk for generating coupling forces that deform the disk out of its nominal plane (40) on opposite sides thereof and into intimate contact with the transducing gaps (32, 32') on the respective heads. The stabilizer devices are positioned in relation to separate radii (r1, r2) depending from the center (c1) of the drive spindle (13) so that a circumferential offset (o1) is established that permits substantially separate interaction of the air bearing surfaces with the disk.
