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.

A method for measuring the clearance of a slider over a rotating disk by inducing a collision between the slider and the disk is described. After the normal flying height of the slider is established, the slider is driven into a collision with the rotating disk surface by applying a DC or AC voltage between the slider and the disk. The clearance data can be extracted from the induced collision by measuring a parameter, such as the change in the amplitude of the readback signal from the magnetic sensor, which is related to fly-height at the normal fly-height and at the disk surface. The two data points can then be used to derive the clearance. One embodiment uses a single beam interferometer to derive the vibrational displacement of the collision event.

A self-contained OCR system includes a housing holding a scanner for outputting a digitized representation of information on paper documents, and a processor in the housing for executing an OCR module to generate ASCII text from the digitized representation. The housing also holds a hard disk drive for storing the text. External devices are not needed to transform the paper-borne text to electronically-stored text.
摘要:
A method for creating a disk drive. A slider is installed in a disk drive having at least one unlubricated disk. The slider is designed to be in initial contact. The slider is burnished to the final design point. A vapor phase lubricant reservoir system is installed in the drive either before or after the burnishing step.

A method for creating a hard drive includes installing a slider in a disk drive having at least one disk lubricated with a first stage lubricant. The slider is designed to be in contact with the disk at initial use. The slider is burnished. A second stage lubricant is added to the disk after the burnishing step. The first stage lubricant provides less lubrication than the second stage lubricant, allowing the slider to be burnished in a controllable manner during the burnishing step. The second stage lubricant then provides lubrication to the disk during use by the end consumer.

A medical monitor is disclosed for implantation in a human body for monitoring biological activity and states as detected by implanted sensors. The medical monitor includes an enclosure surrounding at least one hard disk drive, and also includes a transmitter and a receiver for producing and transmitting signals in the radio frequency range. The medical monitor is in communication with the sensors, by which information on biological activity and states is stored on the one or more hard disk drives. It also includes a recharging system including at least one rechargeable battery and an induction electronics interface.

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.

A device for extending an event time of a physical shock imparted on an electronic device. The device includes a rigid or semi-rigid frame and a resiliently elastic material coupled to the frame, the resiliently elastic material suspending an electronic device with respect to the frame. The resiliently elastic material may be in the form of a sheet, a strap, a rib, and combinations thereof. One preferred resiliently elastic material is a polymeric material.
摘要:
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. In another example, the heat source is comprised of a separate heating element which is formed on or within the magnetic head (which may be the same heating element utilized for thermal-assist writing to the magnetic disk). In yet another example, heat for thermally bonding lubricant is generated by reading data from a data block on the magnetic disk and writing the data back to the data block in a repetitive fashion.
