摘要： A tape cartridge for increasing tape drive head performance is provided. The tape cartridge comprises a cleaning tape, a tape guide arrangement that guides the cleaning tape within the cleaner cartridge, a cleaning fluid application arrangement that applies cleaning fluid to the cleaning tape within the cleaner cartridge, and a cartridge memory that stores cleaning count and motor taches count information. The tape guide arrangement is operable to bring the cleaning tape in contact with the cleaning fluid application arrangement to apply the cleaning fluid onto the cleaning tape when the cleaning tape is subject to a first tension level and avoid the contact with the cleaning fluid application arrangement when the cleaning tape is subject to a second tension level to prevent application of the cleaning fluid onto the cleaning tape.

摘要： An apparatus for disposal of electronic devices includes a transport mechanism for transferring the storage devices through the apparatus. A scanner scans or reads the devices as the devices move through the apparatus, a sanitizer for degaussing or erasing the storage devices, and a destruction mechanism for physically deforming the devices. The apparatus is further configured to receive scanned information from the scanner, determine identification information for the devices based on the scanned information, and update status information of the devices during movement of the devices between the scanner, sanitizer, and destruction mechanism.

摘要： Three systems for the destruction of the data storage portion of electronic media storage devices such as hard disk drives, solid state drives and hybrid hard drives. One system utilizes a mill cutter with which the hard drive has relative motion in the direction of the axis of the mill cutter to destroy the data storage portion. A second system utilizes a laser to physically destroy the data storage portion. The third system utilizes a chemical solvent to chemically destroy the data storage portion.

摘要： An apparatus comprises a slider configured for writing data to and reading data from a magnetic recording medium and for heat-assisted magnetic recording. The slider comprises a heater configured to receive an AC signal and to cause oscillation in a spacing between the slider and the medium, and a contact sensor situated on the slider and configured to produce a DC response signal. A detector is coupled to the slider and configured to measure an amplitude of a spike in the DC response signal, calculate a ratio between the spike amplitude and an amplitude of the DC response signal, and detect contact between the slider and the medium in response to the ratio exceeding a predetermined threshold.

摘要： A cleaning tape has a base tape made of a synthetic resin and a cleaning layer formed on a surface of this base tape. The cleaning layer has a binding agent and a large number of spherical particles dispersed in the binding agent in a single particle layer. Such a cleaning tape is capable of removing very small unwanted protrusions and particles on the surface of a target object such as a magnetic hard disk without forming scratches.

摘要： A cleaning structure for removing dust is constituted of a guiding member having a sliding surface for guiding run of a tape, and a vacuum pressure supply source for making a vacuum pressure effect on a suction space provided inside the guiding member and so on. At the sliding surface of the guiding member, a suction port for making the suction space communicate with an external space is formed, and the opening edge of the suction port on the downstream side in the tape running direction is served as a first dust removal portion for removing dust on the tape surface. The guiding member has a guiding wall having a contact surface which guides at least one tape edge of a tape, and the contact surface is served as a second dust removal portion for removing dust adhering to the tape edge.
