Abstract: A method and system for sensing the current applied to the motor of a data storage device and determining whether a shock event has occurred by processing the sensed current levels.

Abstract: A storage device includes a processor, a vibration detecting sensor that detects a vibration, a plurality of disk drives, and a disk control device that causes the processor to perform an operation of generating a vibration for a disk drive selected from among the plurality of disk drives so that the generated vibration vibrates in a cycle that is shorter than a cycle of the vibration detected by the vibration detecting sensor.

Abstract: A portable electronic device having an outer housing, a component, and a shock-absorption assembly is disclosed. A shock-absorption assembly located within the outer housing and coupled to the component can include one or more elements adapted to dampen a mechanical shock to the component. The shock-absorption assembly elements can be mounted to corners and/or edges of the component. Shock-absorption assembly elements can include a first portion comprising protrusions that provide initial damping of the mechanical shock and a second portion comprising an elastic block that provides final damping of the mechanical shock.

Abstract: An information processing apparatus includes: a hard disk drive unit including a hard disk drive configured to read various data from and write various data in a magnetic disk incorporated therein; a housing of an apparatus main body configured to hold the hard disk drive on a substrate to be freely attached and detached; and a hard-disk-drive holding member provided in the hard disk drive unit, configured to include a first anti-vibration member having vibration damping properties disposed on a predetermined surface parallel to a disk width direction of the magnetic disk and fix and hold the hard disk drive in a state in which the first anti-vibration member is sandwiched between the hard disk drive and the predetermined surface, and formed of a metal member.

Abstract: A fastener for securing computer storage devices is revealed. The fastener is arranged at a storage device of computers. The fastener for securing computer storage devices consists of a first fix member, a second fix member and a connection part. The first fix member and the second fix member respectively are disposed on two sides of the storage device. The first fix member as well as the second fix member respectively has at least one first groove and at least one second groove. A first mount member and a second mount member of a housing respectively are mounted into the first groove and the second groove. The storage device is fixed by the first fix member and the second fix member. The storage device is mounted in the housing of computers more stably by the assembling of the first mount member and the second mount member with the first groove and the second groove respectively.

Abstract: There is provided a motor. The motor includes a shaft rotatably installed and supported by a sleeve, a rotor case coupled with the shaft and on which a disk is mounted, and a pressure difference generation portion disposed in a space between the disk and the rotor case and generating a pressure difference using airflow in the space.

Abstract: A hard disk drive is disclosed including at least one air filter mounted on a shroud wall of the base and at least two disk dampers where at least one disk damper covers a fraction of the maximal covering angle configured with the air filter to optimize both the air filter and disk dampening. Methods of manufacturing the hard disk drive are also disclosed.

Abstract: According to one embodiment, a disk drive includes a housing comprising a base and a top cover combined to the base. The housing contains a motor configured to rotate about a rotational center and a pivot as a rotational center of a head actuator. The top cover includes a first rib. The first rib is configured in a shape comprising a first center in a triangular region. The triangular region has vertexes on a first point corresponding to the rotational center of the motor, a second point corresponding to the pivot, and a third point at a central portion of one side on an opposite side of the second point with respect to an axis extending longitudinally relative to the housing through the first point.

Abstract: A motor unit for use in a disk drive apparatus includes a motor portion, a housing member including a through hole defined therein, and a circuit board. The motor portion includes a rotating portion, a base portion, and a stator fixed to the base portion. The circuit board is arranged to extend from an outside of the motor portion to an inside of the stator through a gap defined between the stator and the base portion. The circuit board includes a connection portion arranged radially inward of the stator. A plurality of lead wires of the stator is connected to the connection portion.
