A video coder is configured to form, in a symmetric motion vector difference mode, a List 0 (L0) base vector using a L0 Advanced Motion Vector Prediction (AMVP) candidate list and a List 1 (L1) base vector using a L1 AMVP candidate list; determine a refined L0 motion vector and a refined L1 motion vector by performing a decoder-side motion vector refinement process that refines the L0 base vector and the L1 base vector; and use the refined L0 motion vector and the refined L1 motion vector to determine a prediction block for a current block of a current picture of the video data.

The present disclosure includes embodiments of an electronic device having a housing that defines an interior gas space, and desiccant disposed therein. The desiccant includes one or more zeolite compositions to manage the relative humidity of the interior gas space.

A heat-assisted magnetic recording device is disposed in a hermetically sealed enclosure. The device includes a slider comprising a reader, a writer, and an optical waveguide configured to couple light from a light source to a near-field transducer situated at or near an air bearing surface of the slider. The near-field transducer comprises an enlarged portion and a peg extending from the enlarged portion in a direction of the air bearing surface. A fill gas is provided within the enclosure. The fill gas comprises a mixture of a low-density, inert gas and at least one gas that oxidizes carbon, where the total carbon oxidizing gas concentration of the fill gas is 3-50% by volume. In certain embodiments, the fill gas comprises a hydrogen concentration sufficient to retard oxidation of the peg when the peg is at an operating temperature associated with write operations.

A data storage array has a backplane at the base of an enclosure. A plurality of data storage drives are coupled to connectors of the backplane. A hot-swappable protocol expander module is coupled between the drives and the backplane through a top of the enclosure or to the backplane through a side of the enclosure.

A data storage drive includes a rotatable data storage medium, and a head communicatively couplable to the data storage medium. The head includes a temperature sensor and a heater. The data storage drive also includes a ramp for supporting the head when the head is moved away from the data storage medium, and a controller. The controller is configured to obtain first temperature sensor measurement values for different head heater power settings when the head is positioned on the ramp, and is configured to determine an internal pressure of the data storage drive as a function of the first temperature sensor measurement values.

Provided is a magnetic tape cartridge including: a case in which a magnetic tape is accommodated; and a storage medium provided in the case, in which the storage medium stores tension allowable range related information regarding an allowable range of tension applied to the magnetic tape.

A magnetic tape cartridge includes a case in which a magnetic tape is accommodated and a storage medium provided in the case. At least one of reading or writing of data is performed by a plurality of magnetic elements, which are linearly disposed, with respect to the magnetic tape pulled out from the case. A disposition direction of the plurality of magnetic elements is tilted toward an entire length direction side of the magnetic tape with respect to a width direction of the magnetic tape. The storage medium stores tilt feature information indicating a feature of tilt of the disposition direction with respect to the width direction.

A thermally and structurally optimized disaster resistant housing for a vertically stacked array of computer digital data storage devices such as hard drives is provided. An external, fire resistant housing has an internally mounted water resistant enclosure for the array. The water resistant enclosure includes a plurality of much thicker plates than known which significantly increase dissipation of heat and simultaneously greater increase the crush and impact load resistance of the device. An automatic method is also provided for producing complex molded gypsum or cement components.

In an approach for preventing damage to a tape library, a processor receives a first sensor reading, wherein the first sensor is located within a tape library. A processor receives a second sensor reading, wherein the second sensor is located external to the tape library. A processor determines that the second sensor reading is greater than or equal to the first sensor reading. A processor receives an indication that a door to the tape library is open. Responsive to receiving the indication that the door to the tape library is open, a processor disables a fan.

A ring-shaped glass spacer is configured to be arranged in contact with a magnetic disk in a hard disk drive apparatus. A surface resistivity of a surface of a glass material of the glass spacer at 22 (° C.) is lower than a surface resistivity of an inner portion of the glass material at 22 (° C.).
