摘要： A nanoimprinting configuration includes a UV light diffuser that randomizes a collimated UV light beam so as to diffuse the shadowing effect from any defect object that resides in the UV optical path. In addition, a combination center circular pad and outer ring-shaped pad form a donut-shaped “non-contact” area between the two pad pieces. The size and shape of the two pad combination are designed to avoid direct gel pad contact above the patterned imprint zone on the disk substrate. The purpose of the gel pad, non-contact configuration is to eliminate any possible surface deformation incurred along the loading column and thereby avoid the elastic propagation of any deformations to the stamper resist surface.

摘要： A servowriting method for a patterned-media magnetic recording disk uses a special position error signal (PES) alignment pattern located in each servo sector. A gross feedforward correction signal to compensate for gross eccentricity of the disk relative to the center of rotation of the servowriter spindle is applied to the actuator. With the gross feedforward correction applied to the actuator the read head generally follows a data track centerline and will detect signals from PES alignment fields as each servo sector passes the read head. This results in a readback signal at each servo sector that represents the fractional track-width radial offset of the read head in that servo sector from a data track centerline. The set of radial offsets for all of the servo sectors is used to modify or fine tune the gross feedforward correction signal that is applied during the servowrite process. This enables the servowriter write head to then precisely follow a track centerline so that the discrete islands in the PES fields can be magnetized according to the desired pattern.

摘要： Servo patterns and associated methods of fabricating servo patterns are described. For patterned storage media, data sectors and servo sectors may be patterned using self-assembly. In one embodiment, self-assembly is used to form a first array of islands and a second array of islands in servo sectors that are track-wise offset. A servo writing process is then performed to write a desired servo pattern in the arrays, such as for burst fields, synchronization fields, etc.

摘要： A magnetic recording disk drive has disks with identical pre-patterned servo patterns on their front and back surfaces and a servo control system for positioning the read/write heads using the servo signals from the identical servo patterns. The servo sectors on the two disk surfaces form identical patterns of angularly spaced arcuate-shaped lines that extend generally radially across the data tracks. The arcuate-shaped lines on one surface, the front surface, generally replicate the path of the recording head as it is moved across the data tracks by a rotary actuator, so that there is a constant sampling rate of the servo sectors on the front surface regardless of radial position of the head. However, the arcuate-shaped lines on the other surface, the back surface, do not replicate the path of the recording head so the servo sampling rate is not constant but varies with radial position of the head. The disk drive servo control system implements a method to enable track seeking from one data track to another data track, regardless of whether the initial disk surface and the destination disk surface are front or back surfaces.

摘要： A method for patterning and forming very small structures on a substrate such as a wafer. The process uses a difference in surface energy between a mask and the substrate to selectively deposit a hard mask material such as a metal onto the surface of the substrate. The mask can be formed extremely thin, such as only an atomic mono-layer thick, and can be patterned by ion beam photolithography. The pattern can, therefore, be formed with extremely high resolution. The thin mask layer can be constructed of various materials and can be constructed of perfluoropolyether diacrylate (PDA), which can be dip coated to and exposed to form a desirable positive photoresist mask layer.

摘要： A data recording medium, such as a magnetic recording hard disk, has data tracks with pseudo-random binary sequences for the servo information used to control the position of the recording head in the disk drive. A first pseudo-random binary sequence (PRBS) and a second PRBS identical to the first PRBS but shifted by a portion of the period of the first PRBS are located between the track boundaries in alternating tracks in a first region of the servo pattern and between the track centers in alternating tracks in a second region spaced along the track from said first region. A servo decoder in the disk drive has two correlators, one for each PRBS. Each correlator outputs a dipulse when its PRBS repeats. The difference in amplitude of the dipulses represents the head position signal. The dipulses also control the amplifier for the signal read back by the head and the timing of the track identification (TID) detector.

摘要： A contact magnetic transfer method for forming a pattern of magnetized servo regions in the magnetic recording layer of a rigid magnetic recording disk uses a flexible master disk and a differential gas pressure to press the patterns of the master disk against the slave disk. The master disk is a flexible plastic film with islands of magnetic shielding material extending above the film surface, the islands forming a pattern representative of the servo pattern to be formed in the recording layer of the disk. The plastic film is sealed at the outer periphery of the opening of a pressure chamber with the islands located outside the chamber. The previously DC-magnetized slave disk is brought into gentle contact with the islands and gas pressure inside the chamber is increased to slightly above atmospheric. This controlled pressure presses the islands into contact with the slave disk, at which time a magnet magnetizes the regions of the recording layer not aligned with the islands in the direction opposite to the original DC-magnetized direction. The magnet is located on a rotatable stage within the chamber beneath the plastic film and mounted so that the length of the gap is in the radial direction corresponding to the radius of the slave disk.

摘要： High power thyristor-type devices comprising a first layer of p-type doped semiconductor alloy aluminum gallium nitride, a second layer of n-type doped aluminum gallium nitride with lower aluminum content than the first layer, a third layer of p-type doped aluminum gallium nitride with a higher aluminum content than the second layer, and a fourth layer of aluminum gallium nitride of n-type doping. The difference in hole and electron energies (band offsets) across the interface between aluminum gallium nitride and gallium nitride are such that hole and electron transfer are enhanced from aluminum gallium nitride to gallium nitride, or hole and electron transfer are suppressed from gallium nitride to aluminum gallium nitride. Aluminum content in layers 1 and 2 is chosen such that hole transfer in the forward biased conduction state of the device is enhanced, and suppressed in the reverse biased blocking state of the device. Aluminum content in layers 2 and 3 is chosen such that hole transfer in the forward biased blocking state of the device is suppressed, which reduces leakage current and enhances hole transfer into layer 2 when the device is changing from the forward biased blocking state to the forward biased conduction state. Triggering of the device may be provided by a gate contact to the third layer. Various exemplary embodiments are disclosed.
