摘要： A patterned magnetic recording medium has discrete data islands arranged in spaced-apart tracks, with the tracks being arranged in multi-track groups or “hypertracks”. The islands have an equal island-spacing (IS) distance in the along-the-track direction and within each hypertrack the tracks are spaced-apart an equal track-spacing (TS) distance. If there are N tracks in a hypertrack then the islands in each track of a hypertrack are shifted in the along-the-track direction by 1/N times IS from the islands in adjacent tracks in the same hypertrack. The read and write heads have a lateral or cross-track width generally equal to the cross-track width of a hypertrack, so the read and write heads span all the individual tracks in a hypertrack. The hypertracks are spaced apart cross-track direction by a group-spacing (GS) distance, with GS being greater than TS. The islands in a hypertrack may be shifted in the along-the-track direction by approximately ½N times IS from the islands in adjacent hypertracks.
摘要翻译：图案化磁记录介质具有布置在间隔开的轨道中的离散数据岛，轨道被布置成多轨道组或“超曲线”。这些岛在沿轨道方向上具有相等的岛间距（IS）距离，并且在每个超曲线内，轨迹间隔相等的轨道间距（TS）距离。如果超轨迹中存在N个轨迹，则超轨迹的每个轨道中的岛屿沿着轨道方向从同一超轨迹中的相邻轨道中的岛屿移位IS / N次IS。读写头具有通常等于超曲线的横向轨道宽度的横向或横向轨道宽度，因此读和写头跨越超轨迹中的所有单个轨道。超曲线是跨距离方向间距（GS）距离，GS大于TS。超轨迹中的岛屿可能沿着轨道方向从相邻超轨道中的岛屿移位约1/2倍的IS。

摘要： A magnetic recording disk drive uses a disk having pre-patterned servo sectors extending generally radially across the data tracks. The servo sectors include at least two position error signal (PES) bursts or fields. The phases of the PES fields in the servo readback signal are demodulated to generate a PES to control the disk drive actuator for positioning the read/write heads. Each field contains generally radially directed magnetized stripes, with each stripe comprising a plurality of islands forming a zigzag pattern. The stripes have alternating polarity of magnetizations in the along-the-track direction. In one implementation there are four fields: a first pair of fields A and B wherein the zigzag pattern of the radial stripes in field A is the mirror image about a radial line of the zigzag pattern of the radial stripes in field B, and a second like pair of fields C and D, but wherein the radial stripes in fields C and D are shifted radially by one-half the island radial height from the radial stripes in fields A and B.

摘要： A magnetic recording disk drive uses a phase-quadrature position-error-signal (PES) pattern and a servo signal demodulator that is insensitive to clock errors and phase-misalignment errors. The disk has angularly-spaced servo sectors, with each servo sector having radially-spaced servo tracks that contain a phase-quadrature pattern of servo blocks. A first band in each servo sector contains two generally like patterns radially-spaced in the servo track with the second pattern phase-shifted 90 degrees along-the-track from the first pattern. A second band in each servo sector is spaced along-the-track from the first band and also has two patterns like those in the first band, but with the phase shift of the second pattern being in the opposite direction to the phase shift of the second pattern in the first band. The demodulator calculates the true amplitudes of the servo signal from the measured amplitudes of the servo signals from each band to thereby remove clock errors and phase-misalignment errors.

摘要： An apparatus (and a method for producing the same) for preventing internal vibrations produced as a result of rotary motion at a predetermined frequency within a device mounted in an enclosure from being translated into resulting rotary motion of the device comprises n vibration isolation mounts located between the device and the enclosure, said vibration isolation mounts having stiffness characteristics and being positioned so that rotational motion of the device at the frequency of the rotary motion is eliminated. The vibration isolation mounts are arranged and configured so that when the rotary motion produces linear and rotational forces, the net moment of all forces about the center of gravity of the device is equal to zero. The vibration isolation mounts may be isotropic. The isolation mounts may have different stiffness's. Three or more mounts may be used. Alternatively, the vibration isolation mounts may have the same stiffness's but their positions may be varied. An additional mass may be added to change the location of the center of gravity of the device. The vibration isolation mounts are preferably comprised of a material which provides damping of approximately ten percent of critical damping.
