The present disclosure generally relates to a tape embedded drive having a plurality of feedthrough connectors. The feedthrough connectors are symmetrically placed within the tape embedded drive such that regardless of whether an even or odd number of feedthrough connectors are present, the feedthrough connectors are symmetrical about a centerline of the tape embedded drive. In such a layout, the tape embedded drive is more stable due to symmetrical mass balance. Additionally, the tape embedded drive is more cost effective to produce.

Tape embedded drive with multiple feedthrough connections

The present disclosure generally relates to a voice coil motor (VCM) yoke for a data storage device. The VCM yoke has a unitary body turned back on itself at opposite ends to form a 'C' shape. The unitary body is electrically conductive. The body has a substantially flat inner surface upon which the coil is disposed. The unitary body also has a substantially flat top and a substantially flat bottom surface. A coil is disposed within the turns of the unitary body. The VCM yoke can be coupled to an actuator block using one or more fastening mechanisms that extend through openings in the VCM yoke.

Double bend VCM yoke structure

The present disclosure generally relates to a head positioning assembly in a tape embedded drive. The tape embedded drive has two reels as well as four guide rollers. The reels and guide rollers are arranged within the tape embedded drive so as to position the head positioning assembly as close to the center of the tape embedded drive as possible. In so doing, the reels, guide rollers, and head assembly are more stable which reduces or even eliminates shock and vibration to the tape embedded drive.

Head positioning assembly for tape embedded drive

The present disclosure generally relates to a voice coil motor (VCM) yoke assembly mounted to an actuator block for a data storage device. One or more fastening mechanisms couple the VCM assembly to the actuator block. The fastening mechanisms are coupled to the VCM assembly by one or more soft mounts. The one or more soft mounts reduce undesirable movement of the magnetic recording head by spacing the VCM assembly from the actuator block, yet still ensuring the VCM assembly is properly coupled to the actuator block.

Soft mount voice coil motor assembly

The present disclosure generally relates to a lock mechanism for a tape embedded drive. The tape embedded drive comprises an enclosure enclosing a first tape reel, a second tape reel, and a lock mechanism. The first tape reel comprises a first gear, the second tape reel comprises a second gear, and the lock mechanism is disposed between the first and second gears. The lock mechanism comprises a latch lock, one or more latch tips disposed at a first end of the latch lock, a magnet disposed at a second end of the latch lock, and an electromagnet disposed adjacent to the magnet. When the electromagnet is activated, the latch lock moves to an unlocked position. When the electromagnet is de-activated, the latch lock moves to a locked position where the one or more latch tips are in contact with the first and second gears.

Embedded tape reel lock mechanism for tape embedded storage drive

A data storage device is disclosed comprising a reel that is rotated for a first interval in order to expose a first frame of a magnetic tape to a head. The head is actuated in a first and second dimensions over the magnetic tape in order to access the first frame of the magnetic tape.

Data storage device accessing magnetic tape by actuating head in two dimensions

The present disclosure generally relates to an interface connector in a tape embedded drive. The tape embedded drive has two long edges and two short edges. Within the tape embedded drive, there are numerous guide rollers, at least three feedthrough connectors, and two reels. The interface connector is located along one of the short edges and underneath one of the two reels. By placing the interface connector at that location, the tape embedded drive has sufficient real estate for all of the necessary reels, feedthrough connectors, and guide rollers while also ensuring stability of the tape embedded drive.

Interface connector for tape embedded drive

The present disclosure generally relates to a tape embedded drive having the spindles upon which the tape reels are disposed, fixedly coupled at both the bottom and the top to ensure stability of the reels. Furthermore, an additional cover over the spindle can be used to secure the top coupling mechanism and the spindle to the tape embedded drive enclosure to provide additional stability. A sealing cover is then placed over the additional cover to tightly seal the enclosure.

Tape embedded drive with tied spindle structure

Disclosed here is a magnet for use in a motor. The magnet comprises a magnet body. The magnet body comprises a plurality of coated magnetic granules. Each coated magnetic granule of the plurality of coated magnetic granules comprises a magnetic granule and a metallic layer coating the magnetic granule.

Magnet for motor of magnetic storage device

Disclosed herein is a dual actuator magnetic storage device that comprises a housing, magnetic disks in the housing, an interface connector located proximate a first corner of the housing formed by a first short side and a first long side, a first voice coil motor proximate a second corner of the first short side and a second long side, a first carriage arm positioned near the first short side to move the first carriage arm relative to the magnetic disks, a second voice coil motor positioned proximate a second short side along the first long side, a second carriage arm positioned near the second short side and coupled to the second voice coil motor to move the second carriage arm. The interface connector is recessed into a base of the housing along the first short side to be near the first long side to provide electrical communication through the housing.

A zoom lens includes in order from an object side to an image side, a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and a third lens unit having a negative refractive power. At the time of zooming, distances between the lens units change, and a distance between the first lens unit and the second lens unit at a telephoto end is shorter than a distance between the first lens unit and the second lens unit at a wide angle end, and an aperture stop is disposed on an image side of an image-side surface of the first lens unit, and on an object side of an image-side surface of the second lens unit, and the zoom lens satisfies the conditional expressions.

A waste heat power generation device having: an evaporator that recovers waste heat energy to evaporate a working medium; an expansion turbine generator that generates electric power with the working medium being supplied from the evaporator; a condenser that condenses the working medium discharged from the expansion turbine generator; a pump that feeds the working medium condensed in the condenser toward the evaporator; a measuring device that measures the amount of power generated by the expansion turbine generator per unit time; and a control device that controls the driving of the pump based on the measurement result of the measuring device.
