Abstract: Techniques are described for securing data on data cartridges, such as a Linear Tape-Open (LTO) data cartridge. The techniques include modifying a portion of a cartridge memory (CM) chip of the cartridge in a way that a cartridge drive will be unable to access the data cartridge and to prevent modification of the CM chip by the cartridge drive. In one embodiment, a system includes a data cartridge including a CM chip, a chip reader to read data from and write data to the CM chip, and a computing device to control the chip reader. The computing device causes the chip reader to read data from the cartridge memory chip of the data cartridge and to modify a portion of memory of the chip to prevent unauthorized reads and writes to the data cartridge, without rendering the modification irreversible.

Abstract: 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.

Abstract: 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.

Abstract: Systems and methods for prevention of condensation of ambient water vapor due to evaporation of frozen carbon dioxide particles used to clean data storage tapes. Various embodiments maintain conditions under which condensation cannot form in the ambient environment immediately surrounding a portion of a rigid surface on which the tape is maintained in thermodynamic contact and under tension (e.g., a metallic capstan around which the tape is wrapped).

Abstract: 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.

Abstract: 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.

Abstract: An aquarium fish feeder and a method of feeding fish with a fish feeder. The fish feeder includes mesh walls, a stiffening member and a suspension device. The feeder receives fish food, which is urged against a mesh wall, and the feeder is submerged in water in an aquarium. Fish feed by eating food through the mesh or by eating food that protrudes through the mesh. After the fish have eaten, the container with uneaten food may be removed to prevent fouling of the aquarium water. The stiffening member allows the feeder to be configured and held in a desired shape to allow greater access to the feeder for a greater number of fish. The suspension device permits the feeder to be suspended above the aquarium bottom.

Abstract: 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.

Abstract: The present invention includes a method of creating a shaped image in a workpiece using a high energy source, with the method comprising positioning a layer proximate the workpiece such that the layer prevents debris from the workpiece from dispersing, and directing radiation from the high energy source through the layer to the workpiece, the layer substantially transparent to radiation emitted by the high energy source such that the high energy source is capable of forming the shaped image.

Abstract: Recording disk, such as a data recording disk, having:1. annular main body having datum surface intended to rest on disk drive turntable;2. hub having a center hole;3. magnetic yoke, generally concentric with the main body and hub; said recording disk being characterized by:A. yoke plate adherend on one side of main body, being radially closer to the center hole than datum surface and adjacent the hub;B. axial spacing between yoke plate and hub; andC. axial spacing between datum surface and the side of the yoke plate away from the yoke plate adherend.Design (keeping disk datum and yoke plate adherend on main body rather than on hub) maintains elasticity of the hub (not restricting it like designs in which yoke plate is glued to hub) giving good disk centering onto disk drive spindle. Preferably, hub is made of material having higher elasticity than main body, and both are integral, i.e., injection molded in intimate contact.Stretched surface recording (SSR) disks can be made with this hub design.
