Abstract: A magnetic recording disk drive has a patterned magnetic recording disk with data blocks of magnetizable material separated by nonmagnetic regions, a read head for reading the magnetized data blocks and generating a readback signal, and a timing circuitry that generates from the readback signal a series of timing pulses. When the read head is over a nonmagnetic region the readback signal is significantly reduced, and this signal reduction is detectable to determine the position of the nonmagnetic regions. The timing circuitry includes a rectifier that rectifies the readback signal, a highpass filter that filters the rectified signal at the frequency of the data blocks, and a peak detector that detects the peaks of the filtered signal and generates a series of timing pulses, each pulse representing a nonmagnetic region.

Abstract: The difference is detected between the outputs from first and second heads in a recording medium drive. The first head is positioned relative to the boundary between a first recording track and a separation track isolating the first recording track and a second recording track from each other. The second head is positioned relative to the boundary between the separation track and the second recording track. A position information specifying the positions of the first and second heads are generated based on the difference. The first and second heads follow the different boundaries, so that the outputs of the first and second heads reliably vary. The difference between the outputs thus reliably changes. An accurate position information can be generated based on the difference. The position information may be utilized in tracking servo control, for example. This enables establishment of the tracking servo control with a higher accuracy.

The methods may further include increasing the seek time to provide an increased seek time in response to the detected temperature exceeding the temperature threshold, generating a current command based on the increased seek time, and seeking the transducer from the initial track to the target track on the disk based on the current command. An apparatus configured to control the seeking of a transducer is also disclosed.

The disk drive includes a drive circuitry that directs a read power level to the slider mover to maintain the head at the read HtD spacing, a pre-write power level to maintain the head at the pre-write HtD spacing, a write power level to maintain the head at the write HtD spacing, and a idle power level to maintains the head at the idle HtD spacing.

Abstract: A head position control device controls the position of a head with respect to a disk where post code is assigned to a servo frame. Servo frames of a disk is constituted by a servo frame not having a post code recorded in an inner side zone and a servo frame having a post code recorded in an outer side zone. The device reads the servo frame, demodulates a current position from the servo frame, drives an actuator according to the modulated position, and controls the position of the head to a target position. While implementing a high TPI, the inspection time for post codes can be decreased with a servo frame occupying ratio in consideration of the data format.

Abstract: A system, method, and apparatus for solving flow-induced track misregistration (TMR) problems in hard disk drives (HDD) are directed to breaking up large-scale eddies, and straightening air flows with honeycomb structures, woven wire screens, and guide vanes or holes. In addition, boundary layer manipulation techniques are applied to the airflow in the HDD, such as boundary layer suction with slots or holes, and wall damping techniques, such as an open honeycomb seal and Helmholtz resonators. These flow-conditioning solutions reduce the turbulence intensity throughout the HDD to reduce TMR. These solutions achieve these goals while minimizing increases in the running torque needed to overcome their inherent rotational drag.

Abstract: A write pole for a read/write head of a disk drive system has a tapered surface on a leading edge thereof. Preferably, the tapered surface has a taper angle of between 0 and 20 degrees from a plane normal to the ABS. By having a write pole with a taper in this manner, sufficient write fields can be achieved even with thinner write pole tips on the ABS surface. By decreasing the thickness of the write pole tip in this manner while maintaining sufficiently high write fields, the skew profile of a write head can be decreased and areal density increased.

If the magnetic recording transducer has a protective layer, that protective layer may contain magnetic particles.

Abstract: An air bearing design enables a slider to fly at a higher fly height when the rotational speed of the disk is reduced to about one-third of its operational velocity. In addition, the slider has a flat profile as it scans the disk surface at a low fly height sigma, and low fly height loss during track seek and high altitude operation. This design also provides write protrusion compensation and thereby mitigates spacing losses due to the write current swelling of the write element protrusion. The leading region of the rear pad of the air bearing is mildly concave. This design produces unexpected results by compressing incoming air flow in such a way that, even under two very different velocities, good air bearing lift is generated while compensating for write element protrusion.

Abstract: A magnetoresistive read/write head includes an integral top and side shields deposited on top of and substantially surrounding the multiple layers of the MR sensor stack. Such a design is particularly advantageous in CPP designs in which the only spacing necessary between the side shields and the bottom shield is due to a gap layer.

In addition, the design is also advantageous in CIP heads having permanent magnet abutted junctions or patterned exchange bias stabilization. In this latter embodiment, it may be possible to reduce the profile of the permanent magnet and any conductors to increase the efficacy of the side shields.

Abstract: Reduce breakdown voltage and control breakdown path for electrostatic discharge to terminals of microelectronic packages, such as no-connect Land Grid Array (LGA) pads. In one embodiment, solder resist openings with a small separation distance are used to provide an air breakdown path between a no-connect LGA pad and the surrounding metal and to reduce the breakdown voltage.

Alternatively, sharp features (e.g., metal traces) with a minimum separation distance can be arranged pointing at each other under the solder resist layer, or other dielectric layer inside the package, to provide a non-exposed breakdown path.
