  • Publication number: 20060146437
    Abstract: Determining a contact condition between read-write head and accessed disk surface inside hard disk drive, where micro-actuator assembly mechanically couples to slider and electrically interacts through signal path. Signal path sensed, creating sensed feedback signal, used to determine contact condition, which indicates when read-write head is, or is not, in contact with accessed disk surface. Means for implementing this process. Contact condition is product of process. The process may respond to contact condition, altering read-write head flying height. Process may be implemented as operations of embedded control system and/or servo controller. Method of predictive failure analysis using the contact condition to estimate performance parameter and create performance degradation warning. Manufacture process collecting contact condition to partly create reliability estimate of the hard disk drive, which may be form of Mean Time to Failure.

  • Publication number: 20060072241
    Abstract: A sealed Hard Disk Drive filled with an inert gas mixture of air, helium, and/or nitrogen provides a wireless data encrypted interface to facilitate data and control transfer with a host system. The wireless interface additionally allows power transfer through Radio Frequency (RF) propagation or electromagnetic induction. Extended measures for vibration, shock, and temperature control are made possible through the use of the wireless interface. Immersion of the HDD into a viscous gel, or other damping material, provides vibration and shock control, while heating/cooling coils provide temperature control.

  • Patent number: 6954327
    Abstract: A method of thermally bonding lubricant over a surface of a magnetic disk in a disk drive involves providing a heat source at an air bearing surface (ABS) of a magnetic head; causing the heat source to be energized to produce heat; and causing the magnetic head to be moved across a surface portion of a magnetic disk so that lubricant is thermally bonded over the surface portion from the heat produced by the heat source. Preferably, this lubricant bonding mode of operation is performed on a regular or periodic basis. Alternatively, the mode is activated based on a predetermined environmental condition (e.g. temperature or humidity) or from an external signal. In one example, the heat source is comprised of first and/or second pole pieces of the magnetic head through which an electrical current is passed.

  • Publication number: 20050192714
    Abstract: A travel assistant device includes a hard disk drive including at least one database, a digital camera, a microphone, a display screen, and at least one speaker. The hard disk drive is provided with database software by which images and sound input from the digital camera and the microphone are stored in the hard disk drive as a personal log database. Images and sound files can be displayed on the display screen and through the speaker, and the personal log database may be updated by additional commentary and images as desired. The database software also retrieves downloaded database information which includes images, sound files and text which act as a travel instructor. Also preferably included is a portable translator device.

  • Patent number: 6934107
    Abstract: A hard disk drive (HDD) capable of controlling its own internal temperature during testing. A test program embedded in the HDD is run only within a pre-determined optimal test temperature range. The internal temperature of the HDD is kept within this pre-determined test temperature range by switching HDD operation modes back and forth between a higher heat generating Rapid Seek Mode and a lower heat generating IDLE mode. The HDD is thus kept within the optimal test temperature range without the use of external heating and/or cooling devices.
