摘要： The present invention provides methods and apparatus for stabilizing data storage media during laser servowriting of optical servo tracks on the media. The apparatus includes a spindle for rotating the media during servowriting, a fixed media platform, and a media support for stabilizing the vertical position of the media during servowriting. The media support may include channels to reduce or control the formation of an air bearing in the area of servowriting to stabilize the vertical positioning of the media. The media support may also include a vacuum slot for drawing a vacuum through the channels.

摘要： Methods and systems for laser etching of optical servo patterns on magnetic data storage media using two or more beams of laser energy produced from a single source of laser energy to produce a servo pattern on the magnetic data storage media. By using two or more etching beams, the time required to produce a servo pattern on the magnetic data storage media can be significantly reduced. Alternatively, each servo track in the servo pattern can be written more than once. The servo patterns thus formed can be read optically or they may be read magnetically using magnetic overwriting (if the servo pattern is formed in a magnetic coating on the media). In either case, the servo patterns are either permanently formed in the media when read optically, or they can be recreated after bulk erasing if they are provided using magnetic overwriting. In yet another alternative, the servo patterns may be read both magnetically and optically, with the magnetic and optical reading occurring simultaneously or sequentially.

摘要： Systems and methods of thermal control in the carbon dioxide cleaning of data storage disks to reduce or prevent condensation on the surface of the media during cleaning with frozen carbon dioxide are disclosed. A hub recess receives at least a portion of the outer flange of the hub to improve contact between the data storage media and a media platform supporting the media. Contact between the media and the media platform may be further improved by drawing a vacuum through openings in the media platform. In addition, drawing a vacuum through a vacuum channel with an annular ring opening about the media platform and a tangential vacuum port may reduce fluttering of the media on the media platform.

摘要： A system for prolonging the useful life of a mask while ablating a pattern into a workpiece. The system includes a workpiece, a debris-blocking layer thereon, a laser directed toward the workpiece, and a mask provided between the laser and debris-blocking layer. The workpiece may be a data storage disk comprising a substrate and a magnetic coating thereon. The laser may be an ultraviolet laser and the debris-blocking layer should be transparent to the light emitted by the laser. The pattern may include concentric or spiral optical servo tracks in the magnetic coating. The debris-blocking layer minimizes degradation of the mask, thereby minimizing the need to clean the mask and prolonging the useful life of the mask.

摘要： A time-based optical servo system includes at least one optical indicator mark located on at least one servo track of a data storage medium. Alternatively, a pattern of optical indicators is repeatedly recorded in the at least one servo track. A servo read head assembly coupled to a transducing head assembly includes two elongate and non-parallel detection devices having a known relative geometry. The detection devices are adapted to detect the optical indicator marks and determine the time period required for each optical indicator mark to pass between the detection devices. This time period is used to calculate the location of the transducing head assembly relative to the storage medium in a translating direction and produce a position error signal (PES) based thereon.
