Abstract: A system for mounting a hard disk drive inside an electronic apparatus in such a way that the hard disk drive is isolated from vibration and noise and heat generated by the hard disk dive is radiated to a cover of the electronic apparatus to prevent overheating. A foam heat transmission sheet is placed between the hard disk drive cover and an outer casing that is mounted to the electronic apparatus and far-infrared ray transmitting and receiving sheets are attached to the outside of the outer casing and to the inside of the cover of the electronic apparatus to transmit heat from the hard disk drive to the exterior of the apparatus.

Abstract: A docking module for conventional small form factor disk drives provides, in one embodiment, space for two such disk drives embedded in tray loaders, within a standard 3.5 inches halve height floppy bay. The docking module provides hot swappable insertion and removal of tray loaders together with disk drives. The bay is provided within a housing member. A button attached to a lever mechanism disconnects the docking module connector from the tray loader connector and partially pull out the loader when the button is pushed; An EMI shield fixedly coupled to the tray loaders each provide a barrier to electromagnetic interference.

Abstract: A portable hard disk drive cartridge comprises a housing defining a receiving space for positioning a hard disk drive therein. The housing further includes a rear bracket detachable attached to the housing. A first substrate having connectors thereon for electrically connecting with connectors of the hard disk drive is attached to the rear bracket. A second substrate electrically is electrically connected to the first substrate and mounted on the other side of the rear bracket. Wherein at least one of the first and second substrates is adjustably attached to the rear bracket so as to make an adjustment along a horizontal direction to mate hard disk drive from different manufacturers.

Abstract: A flexible magnetic disk drive with a built-in USB interface is disclosed. A disk sensor produces an output that, in the event of a change from one disk to another during a SUSPEND state of a SUSPEND/RESUME signal, remains indicative of disk absence from the moment said one disk was unloaded to, at the earliest, the moment the SUSPEND/RESUME signal subsequently gains a RESUME state, for power-saving purposes. In order to enable the computer to know the occurrence of the disk change immediately upon resumption of disk drive operation, the disk sensor output is sampled approximately at the beginning and end of each SUSPEND state, and immediately after the beginning of each RESUME state, of the SUSPEND/RESUME signal. Six different possible histories of disk loading and unloading past each SUSPEND state are ascertainable from every three disk sensor output samples. Each such renewable history datum is stored on a memory in the interface, for delivery to the computer on demand.

Abstract: The present invention relates to a shockproof device of a hard disk drive in which a plurality of springs are mounted on slide rail seats at sides of hard disk drive of notebook computer in order that the hard disk drive is disposed in a hanging arrangement. Besides, the inner five sides (except the hard disk drive extraction side) of the hard disk drive housing are provided with shock-absorbing blocks for improving the shockproof function. In addition, two sides of the hard disk drive housing are fitted with the slide rail seats for the convenient extraction of the hard disk drive. Accordingly, a better shockproof effect is achieved.

Abstract: A portable computer includes a base portion having a hard disc drive bay formed therein and defined by first and second support surfaces. A hard disc drive is mounted on the first support surface of the bay. The drive has a first height and the bay has a second height, greater than the first height. A spacer is provided to engage surface portions of the hard disc drive and also to engage the second support surface of the bay for limiting flexing of the hard disc drive in response to an impact shock acting on the portable computer.

Abstract: An information recording/reproducing apparatus has a controller for setting the apparatus in a ready state in which at least one of information reproduction, information recording and information erasure can be effected after a recording medium is loaded, in the case where an external request has been detected within a predetermined time period. The controller sets the apparatus in a non-ready state after a recording medium is loaded, in the case where an external request has not been detected within a predetermined time period.

Abstract: A portable wireless sound reproduction system includes a first portable housing having a sound signal receiving circuit and controls for processing the sound signal into two signals for transmission by two separate sound signal transmitters located in the same housing. A pair of speakers is detachably connected to the first housing and include receivers for receiving the wireless transmission of signals from the transmitters. The two speakers are adapted to be disposed in side-by-side relation with the first housing completely overlying and detachably connected to each of the speakers.

Abstract: A device for processing optical data comprising:an optical waveguide formed on a substrate,a light source for the laser beam to be admitted into the waveguide,lens means provided on the waveguide for causing the beam propagating through the waveguide to emerge obliquely upward and focusing the emergent beam two-dimensionally,means for receiving the beam reflected obliquely from above,a base provided with the laser light source, the substrate and the light receiving means,a focusing drive mechanism for adjusting the position of the base upward or downward, anda tracking drive mechanism for adjusting the position of the base laterally.

Abstract: A portable message device comprises a box-like housing, including a channel hook mounting bracket, for detachable mounting on the edge a closure of an automobile, or a building, and includes a cassette tape player mounted within the housing for playing a prerecorded message. In one embodiment, the tape player is mounted on one end of the bracket and the speaker for the player, and an activating switch is mounted on the other so that the player can be secured within an enclosure with the speaker and activating switch being externally accessible. The player is activated by a push button on the exterior of the speaker housing and includes control means that automatically stops the tape at the end of the message.

Abstract: Optical data recording apparatus which enhances a playback signal by comparing the lengths of the lands on a recording medium with the lengths of the pits on it and changes the playback signal to represent equality between such lengths.

Abstract: By means of a radiation beam, an apparatus writes or reads information on an information surface of a rotary optical information disc (21), which apparatus comprises an objective frame (16) on which an objective (17) for concentrating the radiation beam to a radiation spot is mounted by means of a parallel guide (19) in such a way that it can move in the direction of its optical axis (18). The objective is protected against dust, contaminants and mechanical damage by means of stationary plane-parallel radiation-transparent shielding means (22), which are interposed between the objective and the rotary information disc, the lens system of the objective being corrected for the optical properties of the shielding means.
