A MEMS-based mano manipulator or nanopositioner is provided that can achieve both sub-nanometer resolution and millimeter force output. The nanomanipulator or nanopositioner comprises a linear amplification mechanism that minifies input displacements and amplifies input forces, microactuators that drive the amplification mechanism to generate forward and backward motion, and position sensors that measure the input displacement of the amplification mechanism. The position sensors obtain position feedback enabling precise closed-loop control during nanomanipulation.

A magnetic storage system includes a disk, a head, an actuator, and a servo controller. The servo controller monitors a value, such as a position error signal (PES) sample value, a predicted PES sample value, and the like, that is based on servo information provided by the head. The servo controller provides a signal to inhibit writing by the head based on a comparison of the monitored value with a threshold, such as a write fault window (WFW), a PES plus Velocity (PPV) threshold, and the like. The servo controller sets the threshold to a first value based on at least one of an on-track track misregistration (TMR) value and a seek settle TMR value. When the servo controller determines that the head is subject to a vibration condition, the servo controller sets the threshold to a second value that is different from the first value.

Performing embedded runout correction for a track on a rotational data storage disk includes measuring written-in runout for the track, selecting a number of revolutions in response to the measured written-in runout of the track, calculating embedded correction values for the track for the selected number of revolutions of the rotational data storage disk, and storing the embedded correction values.

A suspension for a HGA includes a suspension flexure and an out trigger. The suspension flexure has a tongue region having a first flexure part in a tip portion thereof for mounting a trailing edge of a slider and a PZT mounting region for mounting PZT elements. One end of the out trigger is connected to the suspension flexure, and the other end of the out trigger has a trigger support portion which extends above the tongue region so as to support the leading edge of the slider. The structure of the out trigger is capable of stiffening the tongue region of the suspension flexure and, in turns, avoiding the deformation problem and the dimple separation problem during the manufacturing process or in vibration or shock events. The invention also discloses a HGA with the suspension, manufacturing methods of the HGA and a disk drive unit having such HGA.

Methods 300 and 350 are disclosed for fabricating shallow isolation trenches and structures in multi-bit SONOS flash memory devices. One method aspect 300 comprises forming 310 a multi-layer dielectric-charge trapping-dielectric stack 420 over a substrate 408 of the wafer 402, for example, an ONO stack 420, removing 312 the multi-layer dielectric-charge trapping-dielectric stack 420 in a periphery region 406 of the wafer 402, thereby defining a multi-layer dielectric-charge trapping-dielectric stack 420 in a core region 404 of the wafer 402. The method 300 further comprises forming 314 a gate dielectric layer 426 over the periphery region 406 of the substrate 408, forming 316 a first polysilicon layer 428 over the multi-layer dielectric-charge trapping-dielectric stack 420 in the core region 402 and the gate dielectric 426 in the periphery region 406 , then concurrently forming 318 an isolation trench 438 in the substrate 408 in the core region 404 and in the periphery region 406. Thereafter, the isolation trenches are filled 326 with a dielectric material 446, and a second polysilicon layer 452 that is formed 332 over the first polysilicon layer 428 and the filled trenches 438, forming an self-aligned STI structure 446. The method 300 avoids ONO residual stringers at STI edges in the periphery region, reduces active region losses, reduces thinning of the periphery gate oxide and the ONO at the STI edge, and reduces dopant diffusion during isolation implantations due to reduced thermal process steps.

A disk drive includes a rotatable data storage disk, a transducer, an actuator, and a controller. The disk includes information and data tracks that are defined thereon. The transducer is configured to read the information from the disk. The actuator is configured to position the transducer relative to the data tracks. The controller is configured to measure timing between particular information on the disk, to estimate repeatable runout of the disk based on the measured timing, and to compensate for repeatable runout of the disk responsive to the estimated repeatable runout while positioning the transducer relative to a selected track.

A method for performing a bit line implant is disclosed. The method includes forming a group of structures on an oxide-nitride-oxide stack of a semiconductor device. Each structure of the group of structures includes a polysilicon portion and a hard mask portion. A first structure of the group of structures is separated from a second structure of the group of structures by less than 100 nanometers. The method further includes using the first structure and the second structure to isolate a portion of the semiconductor device for the bit line implant.
摘要:
A circuit for measuring respiratory waveform with impedance method and a method and device for resisting electrical fast transient interference are provided, and wherein an output from the peak detector circuit and a reference signal are input to two input terminals of the comparator circuit, an output terminal of the comparator circuit is connected to a control terminal of the electronic switch, and one terminal of the electronic switch is connected to an output terminal of the signal amplifier circuit and the other to an input terminal of the demodulator/amplifier circuit. If a level of the output signal of the peak detector circuit is greater than the level of the reference signal, the electronic switch is switched off in response to an inversion of the output of the comparator circuit so that the interference is isolated from the next stage circuit. The present invention is prone to be implemented with significant effect.
摘要:
A disk drive detects head touchdown based on a magnitude of a position error signal at a discrete frequency. The discrete frequency is one-half the disk rotation frequency or an integral multiple of the disk rotation frequency. The head is heated by turning on a heater at the discrete frequency, thereby injecting bias into a servo system that increases the PES magnitude. In addition, the servo system has a first transfer function for tracking the head during read and write operations and a second transfer function for tracking the head during head touchdown detection. The second transfer function has smaller vibration rejection than the first transfer function so that the disk drive is less sensitive to vibration during read and write operations than during head touchdown detection.
