摘要： A mold assembly for forming a replica disk in a disk molding process. The replica disk includes a formatted surface on both sides. The mold assembly includes a disk substrate cavity defined by a first block having a first major surface, a second block having a second major surface, and an outside edge. The first stamper has an outside edge. The first outer holder includes a first holder edge, the first holder edge extends over the outside edge of the first stamper, coupling the first stamper to the first major surface. A second stamper having an outside edge is coupled to the second major surface. A channel is provided in fluid communication with the disk substrate cavity for allowing disk molding material to enter the disk substrate cavity. Further, a stripper mechanism may be located at the outside edge, wherein the stripper mechanism is moveable relative to the first block and the second block.

摘要： A mold and a process for use in producing data storage articles such as single substrate double-sided disks. In one configuration, a mold for manufacturing a substrate includes a stamper, at least one holder having an interface with the stamper, and a vacuum line for applying a retention force to maintain the interface between the holder and the stamper. In another configuration, the mold includes a demolding line for applying a demolding force to the substrate to aid in separating the substrate from the stamper. The various embodiments of the present invention provide, among other things, easier and faster stamper changeover, substrates and final data storage articles having improved process indicia such as thickness, flatness, inner and outer diameter, and concentricity, and facilitates production of single-substrate double-sided disks.

摘要： A method for manufacturing magnetic recording tape includes applying a front coat including a magnetic component to a substrate to provide a coated substrate. The coated substrate defines a first face and an opposing, second face, the first face extending between a first corner and an opposing, second corner, and the second face extending between a third corner and an opposing, fourth corner. An abrasive surface is moved against the first corner of the coated substrate to abrasively remove a volume of material from the first corner. In particular, the abrasive surface is angularly offset at a substantially non-orthogonal angle from the first face of the coated substrate.

摘要： In one embodiment, the invention is directed toward inline lapping of magnetic tape. The lapping process is performed inline with one or more other magnetic tape manufacturing processes. In this manner, the number of times the magnetic tape is un-spooled and then re-spooled can be reduced. Consequently, the amount of handling of the individual tape pancakes can also be reduced, thus avoiding damage to the edge of the tape, or other damage associated with tape pancake handling.

摘要： A data storage disk cartridge having a dual housing structure includes an inner housing that contains a disk, and an outer housing that contains the inner housing. The inner housing is at least partially removable from the outer housing for insertion into a disk drive. The outer housing remains external to the disk drive, however, except for a portion that is inserted into the drive to provide a docking channel for retraction of the inner housing. A shutter on the inner housing covers a portion of the disk, but is manipulable by the disk drive to uncover the disk and allow drive access. The dual housing structure of the cartridge is capable of significantly improving disk and drive reliability, particularly for recording applications that require higher areal recording densities, such as near field optical recording. In particular, the disk cartridge reduces the accumulation of debris on the disk and drive components. The dual-housing disk cartridge provides a system of partially redundant barriers that significantly reduce the possibility of debris accumulation. The barriers form a hierarchy of cleanliness that stands between the outside environment and the disk and drive components. Consequently, in a preferred mode, the disk is never exposed to the outside environment. The reduced amounts of debris contribute to more consistent optical and mechanical performance of the disk and drive, and thereby enhance data storage reliability.

摘要： A data storage cartridge having a data storage disc locking/restraining mechanism. The data storage cartridge includes a shell defined by a cover and a base, within which a disc and the restraining mechanism are disposed. The restraining mechanism operates to restrain the central portion of the data storage disc against the shell when the data storage disc is in a non-operating position. When the data storage disc is in an operating position, the restraining mechanism is disengaged from restraining the disc by the drive spindle independent of a shutter mechanism.
