Abstract: A disk drive having a head and disk assembly designed to transfer data to and from the disk at very low flying heights, for example 2.5 mu '. Due to factors including shock, disk drive vibration and changes in ambient pressure, the head will occasionally fly below the average flying height during rotation of the disk. At these lower heights, the head may contact asperities protruding from the disk surface. The present invention operates with burnishable disks, such that, during operation of the disk drive and rotation of the storage disk, the repeated contact of the head slider with the higher asperities causes the asperities to be worn down, or burnished. In this way, each of the asperities on the disk surface are reduced to be below the flying height of the head when the head flies at lower than normal flying heights. Thus, the danger of damage to the head and/or disk due to intermittent contact of the head with the otherwise protruding asperities on the disk is removed.

Abstract translation: 一种具有磁头和磁盘组件的磁盘驱动器，其设计用于以非常低的飞行高度将数据传送到磁盘，例如2.5微米。 由于包括冲击，磁盘驱动器振动和环境压力变化在内的因素，磁头有时会在磁盘旋转期间飞行低于平均飞行高度。 在这些较低的高度，头部可以接触从盘表面突出的凹凸。 本发明使用可磨光盘操作，使得在磁盘驱动器的操作和存储盘的旋转期间，磁头滑块与较高凹凸的重复接触导致凹凸磨损或磨损。 以这种方式，当头部飞行低于正常飞行高度时，盘表面上的每个凹凸减小到低于头部的飞行高度。 因此，由于头部与其它突出的凹凸在盘上的间歇性接触而导致头部和/或盘损坏的危险被去除。

Abstract: A multiple actuator disk drive (20) utilizes multiple heads (46a-j, 47a-j) associated with respective ones of multiple actuators (341, 342) to read data from and write data to all tracks on the surface of a disk.

Abstract: An under-the-hub spin motor (7) for a disk drive includes a stabilizer (60) for supporting the outer diameter of the stator (16) to stiffen the base of the spin motor (7). Stiffening the base in the region surrounding the shaft (12) of the motor (7) increases the resonant frequency of the spin motor (7), increasing the tolerance of the spin motor to applied vibrations. The stabilizer (60) may be a ring formed integrally with the base plate (10) of the disk drive or the mounting flange (10) of the motor.
