摘要： The magnetic head of the present invention includes a narrow, high aspect ratio P2 pole tip and a high aspect ratio, fine pitch induction coil. Electroplating trenches (120, 128, 134) for the P2 pole tip (140) and the induction coil (170) are fabricated in a single RIE process step, and the P2 pole tip and the induction coil are thereafter separately plated up into their respective trenches to complete the fabrication of these structures. Briefly, following the fabrication of a P1 pole and the deposition of an insulation layer thereon, a patterned P2 pole tip seed layer (96). An etching mask pattern (112) includes both a P2 pole tip trench opening and an induction coil trench opening. Thereafter, in a single RIE etching step, the P2 pole tip trench is etched through the dielectric material down to the seed layer, and the induction coil trench is etched through the dielectric material down to the insulation layer. The P2 pole tip is then electroplated up into its trench. Thereafter, the induction coil is electroplated (170) up into the induction coil trench. A chemical mechanical polishing (CMP) step is next conducted to remove the excess induction coil material (168) and the RIE etching mask. Thereafter, a patterned insulation layer is deposited upon the induction coil, which is followed by the fabrication of a P2 pole yoke (192) thereupon.

摘要： A unique system and method for ordering commands to reduce disc access latency while giving preference to pending commands. The method and system involves giving preference to pending commands in a set of priority queues. The method and system involve identifying a pending command and processing other non-pending commands in route to the pending command if performance will not be penalized in doing so. The method and system include a list of command node references referring to a list of sorted command nodes that are to be scheduled for processing.

摘要： A process for producing an iron cobalt alloy exhibiting magnetic anisotropy is disclosed. The alloy also exhibits a high magnetic moment, low coercivity and has uniaxial properties, making it suitable for use as the top pole of a magnetic recording head. The change in magnetic properties is brought about through the application of a high bias voltage during the deposition process.

摘要： The invention provides a read/write channel with a diagnostic system for a disk drive. The diagnostic system may process internal and external signals. The read/write channel may have one or more clock generators (360, 362), a digital to analog converter (370), an analog comparator (370), and a successive approximation register (374). The read/write channel may be implemented on an integrated circuit or a complementary metal oxide semiconductor. The read/write channel may be partial response maximum likelihood (PRML) encoding and decoding.

摘要： A method and apparatus for detecting and respond to low-amplitude-write/skip-write events in a disc drive. The invention involves characterizing the gain factor of a variable gain amplifier embedded in the read path of a disc drive during at least two instances in which the read head passes over a servo sector, prior to a write event. Next the write event is executed. After the write event, the gain factor employed by the variable gain amplifier is acquired as the read head passes over the following servo sector. Finally, the acquired gain factor is compared to the characterizaton in order to detect a low-amplitude-write/skip-write event.

摘要： The invention relates to a device for reading and/or writing a disc-shaped information carrier (17), which comprises a support element (25) of a magnetizable material along its circumference. The device comprises an electromagnetic unit (27) for co-operation with the support element and a scanning unit (23) for reading and/or writing the information carrier. By co-operation between the electromagnetic unit and the support element, the information carrier can be rotated about an axis of rotation (73) and positioned with respect to the scanning unit (23) in five degrees of freedom, i.e. in all degrees of freedom except the rotational degree of freedom around the axis of rotation. According to the invention, the electromagnetic unit (27) comprises a single pair of rows (29, 31) of electromagnets (33, 35), which rows are arranged, along an X-axis perpendicular to the axis of rotation (73), on both sides of the information carrier. The electromagnetic unit (27) further comprises a first pair of electromagnets (37, 39) and a second pair of electromagnets (41, 43) which are diametrically arranged with respect to each other, viewed in a middle position of the information carrier (17) along the X-axis and viewed along a Y-axis perpendicular to the X-axis and the axis of rotation, the magnets of the first and the second pair being arranged on both sides of the information carrier, and the magnetic poles (69, 71) of the electromagnets of each pair being arranged at equal distances from the X-axis and, in each position of the information carrier along the X-axis, on one side of a magnetic point of application (M) of the support element. Thus, the electromagnetic unit has a comparatively simple construction and comprises a limited number of electromagnets, so that also the control unit, which is necessary to control the electromagnetic forces of the electromagnets, is simplified.
