摘要： A disk drive includes a rotatable data storage disk, a transducer, and a controller. The transducer is configured to write data on the disk. The controller is configured to receive data from a host device, to measure at least one parameter that is indicative of a time varying characteristic associated with the disk drive, and to write the measured parameter and the data on the disk through the transducer. The time varying characteristic that is measured may include temperature, air pressure, flying height of the transducer relative to the disk, and/or a position error signal (PES) that is indicative of a radial location of the transducer relative to a desired location along a track on the disk. The measured parameters may be embedded within the data that is written on the disk, they may be written in a same track and/or sector as the data, and/or they may be written on a reserved portion of the disk.

摘要： A method of determining side track erasure in a disk drive having a disk and a transducer. A target track and one or more side tracks proximate to the target track on the disk are selected, and recording parameters for recording signals on the target track and each side track with the transducer are selected. Thereafter, signals are recorded on each side track and then signals are recorded on the target track multiple times. A reduction in the integrity of the recorded signals on each side track due to recording signals on the target track multiple times is detected, and the detected reduction in the integrity of the recorded signals on each side track represents the amount of the erasure of the recorded signals on the side track. Recording parameters are changed based on the signal integrity reduction to minimize side track erasure.

摘要： A system and method for decreasing power consumption of hard disk drives through use of an external atmosphere of low density gas, such as helium, is described. An environment container reasonably resistant to diffusion and leakage of helium (container) is erected around an existing hard disk array or server, wherein a helium mixture is pumped into the container. The helium mixture within the container is maintained at a specified concentration via proper tubing and valves which may be manually or automatically controlled. The actual concentration need not be very pure in order to achieve reduced drag over the disks in each of the hard disk drives, thereby achieving reduced power consumption. The environment container is stand alone from the hard disk drives used such that an altered hard disk apparatus is unnecessary.

摘要： The preferred embodiments of the present invention are devices and processes for producing high resolution lithography or pattern formation on the nanometer scale, using a voltage-biased probe that is slider-mounted along with, or separate from but linked to, a magnetic read head within a HDD mechanism. The probe is guided and positioned over a target layer by the motion of the read head which is, itself, guided by signals from servo tracks on a magnetic layer that activate an electromechanical servomechanism within the HDD. An electric field produced by the probe is capable of modifying the surface of the target layer over which the probe flies either directly, or by current induced or thermally induced effects. Targets such as amorphous or crystalline silicon can be hydrogen passivated and the electric field will produce oxidized or anodized lines with nanometer resolution.

摘要： A waveguide structure for a TAMR head is disclosed wherein at least one detection waveguide is formed parallel to a main waveguide and located a gap distance therefrom. A light source transmits light into the main waveguide and towards an ABS/medium interface. A plasmon generator converts light from the waveguide into plasmon waves that are directed onto a magnetic medium. Back reflected light is captured by the main waveguide, partially diverted into a detection waveguide, and transmitted to a photo detector that measures light intensity (IB) which correlates closely to the plasmon wave intensity at the ABS/medium interface. A controller linked to the photo detector is employed to calculate IB as a function of ABS/medium spacing in a non-write condition and this relationship can be used to control and maintain a constant plasmon wave intensity at the ABS during a series of TAMR write processes with a plurality of media.

摘要： A TAMR head is disclosed with a triangular shaped plasmon antenna covered on two sides with a plasmon layer that generates an edge plasmon mode along a vertex of the two plasmon sides formed opposite a main pole layer. A plasmon shield (PS) is formed along the ABS and opposite the vertex to confine an electric field from the edge plasmon mode within a small radius of the edge plasmon tip thereby reducing the optical spot size on the magnetic medium and enhancing writability. An end of a waveguide used to direct input electromagnetic radiation to the plasmon antenna adjoins a PS side opposite the ABS. In one embodiment, a magnetic shield may be formed along the ABS and adjoins the PS so that a first PS section terminates at the ABS and faces the vertex while a second PS section is formed between the magnetic shield and waveguide end.
