A disc tray includes a bottom wall including an outer periphery and an inner rib supporter supporting the lowermost disc from below. The bottom wall is thickened from the outer periphery toward the inner rib supporter. The lowermost disc includes a data recording area, an inner rib, and an outer rib. When the lowermost disc is stationary, the outer rib of the lowermost disc and the upper surface of the bottom wall are separated by a gap. When the lowermost disc is inclined in such a manner that part of the outer rib of the lowermost disc comes into contact with the upper surface of the bottom wall, the data recording area of the lowermost disc and the upper surface of the bottom wall are separated by a gap greater than thickness of the outer or inner rib.

A product according to one embodiment includes a tape having an applicator portion for applying an organic coating to a magnetic head; the organic coating on the applicator portion of the tape; and a lubricant on a data portion of the tape. The lubricant has a different composition than the organic coating. A method for protecting a magnetic head according to one embodiment includes applying an organic coating to a magnetic head using the foregoing product.

A magnetic storage system according to one embodiment includes a magnetic head having a removable organic coating thereon in an amount sufficient for reducing exposure of the head to oxidation promoting materials. The system also includes an applicator in a drive in which the magnetic head resides, the applicator being configured to apply the organic coating directly to the magnetic head without contacting the magnetic head. At least one guide is configured to create a spacing between the magnetic head and the guide, wherein the spacing is sufficient to insert the applicator into the spacing.

The invention relates to a destruction system for destroying a functional layer, which may receive data or perform other functions, such as optical functions, for example, and a related method. The reactants may be interspersed within the functional layer or may be provided in a separate layer adjacent to the functional layer. The reactants are structured to be ignited to destroy the functionality of the functional layer and the data. Ignition may be obtained through a flame or by suitable electrical current in certain embodiments of the invention.

The present disclosure provides systems and methods associated with data storage using atomic films, such as graphene, boron nitride, or silicene. A platter assembly may include at least one platter that has one or more substantially planar surfaces. One or more layers of a monolayer atomic film, such as graphene, may be positioned on a planar surface. Data may be stored on the atomic film using one or more vacancies, dopants, defects, and/or functionalized groups (presence or lack thereof) to represent one of a plurality of states in a multi-state data representation model, such as a binary, a ternary, or another base N data storage model. A read module may detect the vacancies, dopants, and/or functionalized groups (or a topographical feature resulting therefrom) to read the data stored on the atomic film.

A method for protecting a magnetic head according to one embodiment includes applying an organic coating to a magnetic head using a product having an applicator portion for applying an organic coating to a magnetic head. The organic coating is on the applicator portion of the tape, and a lubricant is on a data portion of the tape. The lubricant has a different composition than the organic coating. Another method for protecting a magnetic head includes applying an organic coating to a magnetic head for reducing exposure of the head to oxidation promoting materials; and storing the magnetic head. Another method includes fabricating a tape having an applicator portion for applying an organic coating to a magnetic head for reducing exposure of the head to oxidation promoting materials; applying the organic coating to the applicator portion of the tape; and applying a lubricant to a data portion of the tape.

A magnetic tape cartridge includes a case on which an identifier is displayed, and a storage medium in which reading condition information that is information regarding a condition for reading the identifier is stored. The magnetic tape cartridge can be part of a cartridge management system, a reading method, and a non-transitory storage medium storing a program.

A test deck may be employed as part of a data storage component testing system. A test deck can consist of at least a bottom cover mating to a top cover to define an enclosed testing region configured to house a data storage medium, transducing head, and head suspension. The top cover may have an access port occupied by a door providing access to the enclosed testing region.

Disclosed herein is an apparatus for supporting discs. The apparatus includes an elongated member. The elongated member includes an exterior surface having grooves spaced apart from each other along a length of the elongated member. Each one of the grooves is configured to receive a portion of a corresponding one of the discs. The elongated member includes an interior channel extending along the length of the elongated member. The elongated member includes fluid release portions spaced apart from each other along the length of the elongated member and each having at least one opening extending from the interior channel to the exterior surface. Each one of the grooves is interposed between corresponding adjacent ones of the fluid release portions.
