  • Patent number: 8134795
    Abstract: Approaches for determining the likelihood that a hard-disk drive (HDD) will experience an imminent error in operation, and preventing the same, using an atmospheric pressure sensor are provided. The HDD comprises an atmospheric pressure sensor capable of determining the altitude at which the HDD is currently located. The HDD also comprises a risk assessment component capable of (a) determining an expression of how likely it is that the HDD will experience an imminent error in operation based, at least in part, upon the current altitude of the HDD, and (b) communicating the expression to a user of the HDD. The HDD may optionally comprise one or more of a particle counter, differential pressure sensor, and a chemical vapor sensor for use by the risk assessment component. If the HDD is above a particular altitude, the Thermal Fly-Height control settings of the heads may be adjusted to reduce risk of error.

  • Publication number: 20110075300
    Abstract: Approaches for reducing vibrations, such as resonance vibrations, that are propagated to a hard-disk drive (HDD) head are disclosed. A hard-disk drive may compromise a lead suspension that includes a magnetic read/write head. The magnetic read/write head may be connected to the lead suspension by a plurality of leads. A portion of each of the plurality of leads, such as the solder ball joints, may be covered by a dampening material that is designed to absorb vibrations occurring in the lead suspension to prevent transmission of the vibrations to the magnetic read/write head. Alternately, the dampening material may be applied to other locations, such as the limiter engagements, which can transmit vibrations to the magnetic read/write head.

  • Publication number: 20090167537
    Abstract: A device and system for monitoring the condition of an electrical outlet such as a 110 volt or 220 volt outlet to alert a user to a dangerous situation and to interrupt power to the circuit in the event of the dangerous condition. The device monitors the circuit for degradation to the electrical outlet. The system can include a temperature sensor voltage meter or particle detector (smoke detector) connected with a power outlet. When a parameter of a circuit exceed a predetermined level (indicating the outlet has degraded to an unsafe level) a warning can be reported and if necessary power to the device can be adjusted or interrupted.

  • Publication number: 20080212235
    Abstract: A slider for magnetic data recording. The slider has an air bearing surface with a trailing edge pad that is configured with a series of recesses that damp slider oscillations during use. The series of recesses formed in the trailing pad of the slider reduce slider oscillations by creating localized pressure gradients within the generally high pressure area over the pad. The slider can be configured with a raised primary pad and a secondary raised pad formed on the primary raised pad. A series of recesses formed in the secondary pad prevent slider oscillations, which would otherwise be especially problematic in a slider having such a secondary raised pad and associated higher pressure area thereover.
