Abstract:
Systems and methods are disclosed for managing temperature in a data storage device. A data storage device includes non-volatile solid-state memory, a temperature sensor, a heating device, and a controller. The controller is configured to receive a temperature signal from the temperature sensor indicating a temperature of at least a portion of the data storage device, determine that the temperature is below a first predetermined threshold, activate the heating device to increase the temperature of the at least a portion of the data storage device, and write data associated with a write command to the non-volatile solid-state memory.
Abstract:
In accordance with one embodiment, a method is disclosed that comprises disposing an antireflection material (325) in juxtaposition with a top surface of a slider (320). In accordance with another embodiment, a method is disclosed that comprises disposing an antireflective material between a facet edge (331) of a laser (330) and an incident surface of a waveguide (332). In yet another embodiment, an apparatus is disclosed that comprises a slider and an antireflection material in juxtaposition with a top surface of the slider.
Abstract:
A system in one embodiment includes a substrate; a thin film structure coupled to the substrate, the thin film structure comprising at least one of read transducers and write transducers; a closure; and an electrostatically dissipative adhesive coupling the closure to at least one of the thin film structure and the substrate. The adhesive comprises a mixture comprising: an adhesive material; and electrically conductive particles intermixed with the adhesive material, the electrically conductive particles being present in an amount between 0 and about 10% by weight of a total weight of the mixture. The closure defines at least a portion of a tape bearing surface. Additional systems and methods are also presented.
Abstract:
Giant magnetoresistance structures exhibiting a giant magnetoresistive effect are provided, and apparatuses incorporating said structures. The structures incorporate a giant magnetoresistive element that is surrounded by protective layers that are capable of shielding the element from harsh environmental conditions, thereby enabling their use in harsh environments.
Abstract:
A CDM simulator for a magnetic recording head ca be used for the in situ testing of such heads and also for electrical and/or magnetic characterization. The recording head is disposed in the simulator adjacent a discharge plate of an electrically conductive material with a dielectric layer disposed therebetween. The recording head is resistively coupled to a ground potential. A stored charge is injected into the discharge plate. When the charge is injected, a current transient similar to electrostatic discharge, is developed through the magnetic recording head.
Abstract:
Wear-resistant and low-friction hard amorphous, diamond-like carbon coating (DLC) is formed directly on an external surface of a magnetic recording media sensor (MRMS). The coating demonstrates a high degree of hardness, low friction coefficient and moderate electric resistivity, providing abrasion-proof, low-clogging, static electricity-deterrent properties.
Abstract:
An improved magnetic medium (100, 110) has a metal or semiconductor surface (102, 114) in which the surface of the magnetic medium has an approximate monolayer of fullerene molecules (104) bonded to the metal or semiconductor surface. The bond strength between the fullerene molecules and the surface is stronger than the fullerene-fullerene intermolecular bond strengh. The magnetic media can be used in the production of components for data storage system (200), in particular heads with magnetic transducers (218, 250) and magnetic or optical-magnetic discs (208, 300, 326). In methods for forming the fullerene coatings, an approximate monolayer of fullerene molecules are deposited on a metal or semiconductor surface substantially free of contaminants.
Abstract:
An MR head has a sliding surface to be in contact with a magnetic recording medium and includes a substrate, on which an MR element is formed, and a reinforcement, which are exposed at the sliding surface. To improve the reliability of the MR head, the substrate and the reinforcement are joined with inorganic film, such as multilayer film including a metal layer. Alternatively, the substrate and the reinforcement are joined with adhesive film that is not exposed at the sliding surface.
