摘要： Processes include aligning a disc with a template at a location so that the pattern from the template is transferred to the disc in a relative orientation. The relative orientation provides that when the disc with the transferred pattern is finally assembled into a hard disc drive, an inner diameter of the spindle hole of the disc may be abutted against an outer diameter of the disc drive spindle, and the data-containing patterns on the discs will be aligned concentrically with a center of the disc drive spindle. While the data-containing patterns are aligned concentrically with the disc drive spindle, the substrate itself is allowed to be non-concentric. Still other aspects include a disc having eccentric formations including PIM and one or more of bit patterns and servo information formed on a disc surface, the eccentricity of the formations is determined based on an expected difference between the radius of the spindle hole of the disc and the radius of the spindle on which the disc will be placed during assembly, with the PIM used to determine the angular alignment of the disc with the spindle.

摘要： A method of making a disc for a computer disc drive and a disc made in accordance with the same. The disc includes a deposited magnetic layer of a thin film medium over a disc-shaped substrate. A master pattern having a plurality of tracks is recorded on the disc. Each track on the disc includes a plurality of magnetic islands, each having a size and magnetic properties. The size and/or magnetic properties of one or more of the magnetic islands of each track are modulated such that each track has a modulation frequency, so as to imprint a magnetic topology on the disc. The modulation frequency of each track is either a fundamental frequency or an overtone of the fundamental frequency.

摘要： Magnetic alignment marks are recorded on a recording surface of a magnetic hard disk to mark the location where the disk is abutted against the hub of the spindle of a multiple-disk servo-writer. The alignment marks for each recording surface may be different so as to distinguish between top and bottom disk surfaces so that when the discs are assembled onto the spindle of a disk drive they may be assembled with the proper orientation, i.e., the top surface is mounted “up.” The marks may be large, low frequency patterns that are both written and detected by non contact means other than the servo-track writer's or the disk drive's heads.

摘要： A method and apparatus for scanning a media is described. More particularly, polarization detector and an atomic force microscope are coupled to a common platform indexed to a spindle. Optionally, an optical microscope may be coupled to the common platform. The polarization detector is used to detect a magnetic image, such as at least a portion of a servo pattern, of the media, and the atomic force microscope, which may be aligned using the magnetic image, is used with a magnetic microscopy module to scan the media. Accordingly, magnetic imagery may be achieved with indexing to a single spindle for positional consistency as between equipment. Moreover, the polarization detector may further be configured to detect scattered light for providing topographic imagery of the media.

摘要： A magnetic data storage medium includes a dedicated transducing head contact zone for engaging an air bearing slider, primarily when the disk is stationary. The contact zone is textured with an irregular sequence of spaced apart nodules forming a substantially circumferential, spiral path. The spiral path includes multiple terms that define a uniform radial pitch. The circumferential pitch is irregular, more preferably determined according to pseudo-random function in which the actual spacing intervals vary about a nominal interval, over a range comparable to, but generally less than, the interval. The pseudo-random array can be formed by a texturing process that includes directing a focused laser beam onto the contact zone. The disk is rotated to maintain a constant circumferential speed relative to the laser, and also is translated radially to provide the desired radial pitch. The laser is operated in a continuous wave mode, with an acousto-optic modulator between the laser and disk operated to provide a pseudo-random variance in time intervals between successive laser exposures.

摘要： A magnetic data storage medium includes a dedicated transducing head contact zone for engaging an air bearing slider, primarily when the disk is stationary and also during disk accelerations and decelerations. The contact zone has a dual baseline texture, formed by first creating a recessed region within the transducing head contact zone, and then by forming multiple nodules or other texturing features within the recessed region. The texturing features project upwardly from a recessed surface of the recessed region, and also project above an upper surface of the disk by an amount less than the texturing feature height. Consequently, the texturing features are large enough to counteract stiction due to liquid lubricant meniscus formation, yet also have heights sufficiently low relative to the upper surface to allow reduced transducer flying heights. According to a preferred texturing process, the recessed region consists of multiple individual recesses produced by applying a carbon layer to the disk, then forming cavities by selective laser ablation of the carbon layer.
摘要翻译：磁数据存储介质包括用于接合空气轴承滑块的专用换能头接触区，主要是当盘静止时以及在盘的加速和减速期间。接触区域具有双基线纹理，首先在传感头接触区域内形成凹陷区域，然后通过在凹陷区域内形成多个结节或其它纹理特征而形成。纹理特征从凹陷区域的凹陷表面向上突出，并且还以小于纹理特征高度的量突出在盘的上表面上方。因此，纹理特征足够大以抵消由于液体润滑剂弯液面形成导致的静摩擦，而且还具有相对于上表面足够低的高度，以允许减小的换能器飞行高度。根据优选的纹理化工艺，凹陷区域由通过将碳层施加到盘而产生的多个单独凹槽，然后通过碳层的选择性激光烧蚀形成空腔。

摘要： The present invention relates to a rigid disc substrate for use in a magneto-optical drive, and two methods and apparatus to solve the above-mentioned problems. A method for writing a servo pattern on a magneto-optical rigid media, after the media optical film is deposited. The method involves an image transfer process, wherein a light source provides an energy pulse to heat up the magneto-optical film above its compensation temperature. Light is directed onto the film through a photo mask which has a prewritten servo pattern on it. The image on the mask is transferred to the magneto-optic disc when an external field is applied by a magnetic field generating coil which defines the area illuminated by the source where the pattern is to be written. In an alternative approach, the mask may be in contact with the media while the light exposure and magnetic field are applied. In a further alternative, the image transfer is achieved with a scanning method whereby the light source is scanned through the mask with the aid of a scanning device while the external magnetic field is applied. This scanning method applies equally well with projection image transfer or contact image transfer.
