Abstract: A system for storing data includes a rack, one or more data storage drive assemblies coupled to the rack, and a data control module coupled to the rack. The data storage drive assemblies include one or more drive mechanical modules configured to store data and one or more drive control modules coupled to the drive mechanical modules. The drive control modules control mechanical operations in the drive mechanical modules. The drive mechanical modules and the associated drive control modules are separable from one another without removing the other module from the at least one data storage drive assembly.

Abstract: A system for storing data includes two or more drive mechanical modules configured to store data, one or more drive control modules coupled to the drive mechanical modules, and a data control module. The drive control modules control mechanical operations in the drive mechanical modules. The data control modules access data on the drive mechanical modules.

Abstract: An optical disc drive device has a metallic exterior casing and an internal unit to be housed in the exterior casing. The internal unit further includes an optical pickup unit for performing recording or reproduction of information signals on an optical disc, and a printed wiring substrate on which a connector electrically connected to the optical pickup unit and serving for transmission and reception of electrical signals from and to external electronic equipment is mounted. The exterior casing has an opening for allowing the connector to be exposed outside, the printed wiring substrate has a ground pattern formed to surround the connector, and a fringe portion of the opening of the exterior casing and the ground pattern are in electrical contact with each other. Thus, radiation noise from around wiring lines contained in the optical disc drive device or the like is reduced.

Abstract: A disk-enclosure base that is configured to inhibit formation of adherent solder-flux residue. The disk-enclosure base includes a casting, a through-hole fabricated in the casting, a solder channel, an E-coat layer, and an E-coat-free zone. The E-coat layer is applied to a first portion of an interior surface of the casting. The E-coat-free zone is adjacent to and surrounds the solder channel. The E-coat-free zone also includes a second portion of the interior surface of the casting lying between the solder channel and the E-coated first portion of the interior surface of the casting. The E-coat-free zone is configured to inhibit formation of adherent solder-flux residue. A disk-enclosure-base/electrical-feedthrough assembly that is configured to inhibit formation of adherent solder-flux residue, and a hard-disk drive (HDD) including the disk-enclosure-base/electrical-feedthrough assembly are also provided.

Abstract: An improved hard disk drive of the invention comprises a housing, which comprises a base and a cover. The hard disk drive further internally comprises at least one disk for storage of data within the housing and an actuator for reading and recording of the data on the at least one disk. An electrical connector comprising a flexible circuit extends through an opening in the base and provides electrical contact between electronics external to the housing and one or more components within the hard disk drive. Methods for forming the improved hard disk drives are also disclosed.

Abstract: A data storage system includes one or more hard disk drive systems and an air moving device. The hard disk drive systems may include one or more drive mechanical modules that store data and a drive control module electrically coupled to the drive mechanical modules. The drive control modules may control mechanical operations in the drive mechanical modules. The drive control module includes a circuit board assembly and heat producing components coupled to the circuit board assembly. Air passages on each side of the printed circuit board assembly allow a stream of air to flow across heat producing components on at least one side of the printed circuit board assembly.
