摘要： An apparatus, system, and method are disclosed for fabricating a patterned media imprint master. A substrate and a deposition mask may be fixably attached by an intervening spacing element, such that the substrate and deposition mask act as a unified element during a deposition process. A deposition mask may include a plurality of apertures generated by a conventional lithographic process. Material may be deposited onto the substrate through the deposition mask from more than one deposition source oriented at a unique deposition angle. A resulting substrate deposition pattern thus exhibits a density greater than a deposition mask aperture density while avoiding deposition pattern distortion.

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： Methods of defining servo patterns and data patterns for forming patterned magnetic media are described. For one method, a lithographic process is performed to define a servo pattern in servo regions on a substrate. The lithographic process also defines a first data pattern in data regions of the substrate. The first data pattern is then transferred to (i.e., etched into) the data regions. Self-assembly structures are then formed on the data pattern in the data regions to define a second data pattern. The servo pattern is then transferred to the servo regions and the second data pattern is transferred to the data regions. Thus, the servo pattern is defined through lithographic processes while the data pattern is defined by a combination of lithographic processes and self-assembly.

摘要： A data storage device comprising a storage medium for storing data in the form of marks. An array of probes is mounted on a common frame. The common frame and the storage medium are designed for moving relative to each other for creating or detecting marks. Each probe is assigned a given field within the storage medium for creating or detecting marks in various tracks. A track density is representative of the distance between consecutive tracks. A linear density is representative of a minimum distance between consecutive marks within one track. The data storage device is designed for grouping the probes into various probe classes, each probe class being characterized in that all its assigned probes are controlled with a common track density and in that all its assigned probes are operated in respect of track movement simultaneously. Each probe class is controlled with a different combination of track density and linear density.

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 magnetic recording disk in a disk drive has identical pre-patterned servo patterns on its front and back surfaces. The servo patterns on each disk surface are pre-patterned with a single master template, resulting in the identical pattern on each disk surface. The servo sectors on the two disk surfaces can form identical patterns of angularly spaced arcuate-shaped lines or straight lines that extend radially across the data tracks. However, because the lines on at least one of the disk surfaces do not replicate the path of the recording head, the sampling rate of the servo sectors on that surface is not constant but varies with radial position of the head. To accommodate this, the disk drive's servo control system calculates a timing adjustment from an estimate of the radial position of the head and uses this timing adjustment to adjust the time to open a time window to allow detection of the servo sectors.

摘要： In method of feedback control for active damping of slider air bearing vibrations in a hard disk drive slider, a slider is isolated from ground. A velocity signal is acquired from the slider. The velocity signal is filtered to acquire a vibration signal. The vibration signal is adjusted in amplitude to achieve an amplitude adjusted vibration signal. The amplitude adjusted vibration signal is applied to the slider to actively dampen vibrations in the slider.

摘要： The present invention provides an integrally formed ramp that is used for evacuating the suspension arm of a data storage device. The ramp has sliding portions, each having guiding zones and a landing zone. The boundary between the guiding zones and the landing zone is formed parallel to a reference line, so even if the landing portion had a recessed shape, the sliding portion could be molded with a casting mold by pulling out the casting mold in the direction of the reference line. The necessary portion of a support portion which is formed with the same casting mold as the sliding portions is formed so as not to disturb the pulling-out of the casting mold in the direction of the reference line. The integrally molded ramp is high in fabrication accuracy and excellent in defining an accurate loading/unloading position of the suspension arm.

摘要： A high torsional stiffness low axial deflection stiffness flexible drive shaft apparatus is provided for driving a magnetic tape cassette and includes a drive shaft having opposite ends, a device for engaging the magnetic tape cassette and a pair of flexible diaphragms. A device is connected to one of the drive shaft ends, one of the flexible diaphragms, and is connectable to a motor for transmitting torsional force from the motor to the drive shaft via the flexible diaphragm. Another device is connected to the other end of the drive shaft, the other flexible diaphragm and the tape cassette engaging device for transmitting torsional force from the drive shaft to the engaging device via the other flexible diaphragm. Because the diaphragms are too delicate to handle thrust loads and because the torsional stiffness of the diaphragm degrades rapidly as its center is displaced axially with respect to the outer driving points, a device is operably connected to each torsional force transmitting device for transmitting thrust loads exerted along the axes of rotation of the drive apparatus. With this arrangement the drive apparatus can easily adapt for misalignment of the drive apparatus with the magnetic tape cassette to deliver a reliable rotating force.
