摘要： A control mechanism may control the height and/or position of a read/write head configured to interact with a rotating information storage surface. A topography detection mechanism may detect topography of a side read/write track while the read/write head is interacting with a current read/write track. A memory may store the detected topography. The control mechanism may adjust the height of the read/write head based on the stored topography. The topography detection mechanism may compute the detected topography from gap measurements using a dynamic filter including a model of read/write head dynamics. The control mechanism may be a reactionless control mechanism configured to apply a counterforce to offset movements of the read/write head and/or a slider.

摘要： A head transducer (103), configured to interact with a magnetic recording medium (160), includes a first sensor (105) having a temperature coefficient of resistance (TCR) and configured to produce a first sensor signal, and a second sensor (106) having a TCR and configured to produce a second sensor signal. One of the first and second sensors is situated at or near a close point of the head transducer in relation to the magnetic recording medium, and the other of the first and second sensors spaced away from the close point. Circuitry is configured to combine the first and second sensor signals and produce a combined sensor signal indicative of one or both of a change in head-medium spacing and head-medium contact. Each of the sensors may have a TCR with the same sign (positive or negative) or each sensor may have a TCR with a different sign.

摘要： The invention provides exemplary magnetic recording media, and in particular, flexible metal foil disks, read/write systems having such disks, and methods for making such disks. In one exemplary embodiment, a recording medium is provided which comprises a metallic substrate and at least one sputter deposited film of magnetic material on the substrate. The recording medium has a thickness that is less than about 0.010 inch and the substrate occupies at least 80 % of the thickness. Further, the sputter deposited film is adapted to record and reproduce high areal densities of digital data. In one embodiment, such a recording medium is included in a read/write system to provide a unique recording interface that can resist mechanical shock.

摘要： A method in a disk drive (300) having a permanent magnet (302), a data storage disk, and an actuator assembly (304) coupled to a transducer (308), for spinning down the data storage disk. The actuator assembly is coupled to an actuator motor (310) which is configured, when on, for positioning with a first torque the actuator assembly (304) such that the transducer (308) is disposed over data storage zones of the data storage disk. The method includes moving, using a ferromagnetic structure coupled to the actuator assembly, the actuator assembly to a home position. The home position represents a position of the transducer assembly in which the transducer is disposed over a designated parking area of the data storage. The ferromagnetic structure is configured to be magnetically attracted toward the permanent magnet with a magnetic force which urges the actuator assembly toward the home position with a second torque lower than the first torque. The method further includes holding, using the second torque, the actuator assembly in the home position when the actuator motor is off. Additionally, the method includes applying dynamic braking, using a spindle motor coupled to the data storage disk, to stop the data storage disk from spinning.

摘要： In a discoidal recording medium that is recorded or played back by a recording/playback head mounted on a head slider, the disk surface and/or head slider are also formed with a predetermined pattern of undulation. With the recording/playback head mounted on the head slider placed in contact with the discoidal recording medium, the recording and playback are performed. This makes the recording/playback head and discoidal recording medium unlikely to be worn out and assures good recording and playback characteristics.
