A recording apparatus records movie content onto a DVD. The movie content is encrypted using a different encryption method depending on whether the DVD is intended for consumer use or industrial use. If the DVD is for consumer use, a VIDEO_TS directory is created on the DVD, and the encrypted movie content is recorded in the VIDEO_TS directory. If the DVD is for industrial use, a VIDEO_TS directory and an EWCPS_TS directory are created on the DVD, and the encrypted movie content and message data are recorded respectively in the EWCPS_TS directory and the VIDEO_TS directory. The message data indicates that the movie content cannot be played back by consumer DVD players.

An information storage device includes a housing having a cavity, and a sliding door partially covering the cavity. The housing has a first groove and a second groove on opposite sides of the cavity. The sliding door includes first and second edges adjacent the first and second grooves, respectively. The sliding door also includes first and second tabs protruding from the first and second edges into the first and second grooves, respectively. The first and second tabs define first and second tab lengths measured parallel to the first and second edges, respectively. There are first and second through-slots in the sliding door adjacent the first and second tabs, respectively. The first and second through-slots define first and second through-slot lengths measured parallel to the first and second edges, respectively. The first and second through-slot lengths are greater than the first and second tab lengths, respectively.

An apparatus for holding a media storage disk of a kind having a surface forming a central hole. The apparatus includes a base portion and two arms, each arm resiliently cantilevered and extending substantially perpendicular from the base portion. A disk locating means includes two portions, each having a disk engageable region. The two portions are also articulated to each other about an articulation axis and each portion is pivotally connected to one of the arms, respectively, about a pivot axis, the articulation axis located between the pivot axes. The two portions are moveable in a manner that moves the articulation axis from a side on one side of and between the two pivot axes, wherein the two portions are in a disk securing condition, to a position on the other side of and between the two pivot axes, wherein the two portions are in a disk releasing condition.

A rigid magnetic recording disk drive includes a vacuum pump attached to the disk drive housing for removing air from within the housing so that the disk drive is operated at a reduced internal gas pressure. The pump motor is controlled by control circuitry that receives an input signal representative of the pressure within the housing to enable the pressure to be maintained within a predetermined reduced pressure range. Because spindle motor current has been directly correlated with internal pressure, a signal representative of the spindle motor current is used as the input to the pump control circuitry. The pump control circuitry also prevents the pump from turning on until the spindle motor has reached its stable operating speed, and from turning on when the disk drive is reading or writing data. Because of the reduced internal pressure the disk drive operates at a significantly higher disk RPM with only a minimal increase in power consumption and without any increase in track misregistration.

An optical storage system suitable for optical storage and retrieval of information using a storage medium comprising a substrate, an active layer for retention of the data, and an overlying optical layer, or layers for double-sided. The optical layer serves to produce an evanescent field in or adjacent to the active layer in response to an incident beam of radiation. The evanescent field is frustrated or attenuated by the data in the active layer and produces a signal.

A system for measuring changes in the resistance of a living body includes a resistance measuring circuit, an amplifier circuit and an indicator circuit in which the amplifier circuit includes a calibration circuit to give a generally constant amplitude response to a given measured input. Radio frequency insulators are included to reduce noise in the system. The circuits are operated such that when an overall change in the resistance of a living body occurs, the resistance measuring circuit is adjusted to determine the overall resistance. To account for changes in sensitivity caused by the overall change in resistance, the gain of the amplifier circuit is automatically adjusted to thereby maintain a generally constant amplitude response.

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.

An optical data storage device protector comprised of two concentric rings. An outer ring is located near the outer periphery of the storage device and the inner ring's hole corresponds closely with the storage device's spindle hole. Both rings may be produced in a label sandwiched form having a peel away release liner, an adhesive that is preferably removable, a release coating facilitating removal of the release liner from the adhesive, a preferably high density face material that is adequately porous to receive a decorative finish and a face coating that serves to protect the decorative finish as well as to make the protector water resistant, UV light resistant and durable enough to withstand cleaning using either soap and water or wiper solutions available for device cleaning and reconditioning. The high density face material extends slightly beyond the device's edge affording edge cushioning and protection and also affords an inertial benefit, making the device more dynamically stable and thus skip resistant when used in portable storage device players.
