Western Digital Technologies Assigned Four Patents

Interface connector for tape embedded drive, tape embedded drive with tied spindle structure, electrostrictive control for width of tape-head-array, head assembly with suspension system for tape embedded drive

Interface connector for tape embedded drive
Western Digital Technologies, Inc., San Jose, CA, has been assigned a patent (10,998,008) developed by Uefune, Kouki, Eguchi, Hajime, Kanagawa, Japa, and Takahashi, Toshio, Tokyo, Japan, for an interface connector for tape embedded drive.

The abstract of the patent published by the U.S. Patent and Trademark Office states: 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.

The patent application was filed on June 19, 2020 (16/907,003).

Tape embedded drive with tied spindle structure
Western Digital Technologies, Inc., San Jose, CA, has been assigned a patent (10,997,998) developed by Uefune, Kouki, Kanagawa, Japan, Takahashi, Toshio, Tokyo, Japan, Hayakawa, Takako, and Arai, Yuichi, Kanagawa, Japan, for a tape embedded drive with tied spindle structure.

The abstract of the patent published by the U.S. Patent and Trademark Office states: 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.

The patent application was filed on June 24, 2020 (16/910,512).

Electrostrictive control for width of tape-head-array
Western Digital Technologies, Inc., San Jose, CA, has been assigned a patent (10,997,995) developed by Seagle, David J., Morgan Hill, CA, for an electrostrictive control for the width of a tape-head-array.

The abstract of the patent published by the U.S. Patent and Trademark Office states: The present disclosure generally relates to tape heads for use in a tape drive system. The tape head includes a plurality of servo elements and a plurality of data elements disposed between the servo elements. An electrostrictive material is present in the tape head. Electrodes are coupled to the electrostrictive material to permit a voltage to be distributed across the electrostrictive material. The voltage causes the electrostrictive material to expand, and thus expand the tape head. By expanding the tape head by adding voltage, or contracting the tape head by lowering voltage, the spacing between adjacent data elements can be adjusted to match the spacing between adjacent data tracks on a tape.

The patent application was filed on August 19, 2020 (16/997,701).

Head assembly with suspension system for tape embedded drive
Western Digital Technologies, Inc., San Jose, CA, has been assigned a patent (10,991,390) developed by Kobayashi, Masahito, Ushiko, Japan, for a head assembly with suspension system for a tape embedded drive.

The abstract of the patent published by the U.S. Patent and Trademark Office states: A storage device comprises tape reel(s) holding tape media for storing data, a head assembly, motor(s) configured to actuate the head assembly, a sealed casing, and a printed circuit board assembly, PCBA) configured to control operations of the motor(s). The head assembly comprises a support structure, a head bar with read head(s) and write head(s, and a suspension system connecting the head bar to the support structure. The sealed casing encloses in its interior the tape reel(s, the head assembly, and the motor(s). Meanwhile, the PCBA is mounted on an external surface of the casing.

The patent application was filed on March 26, 2019 (16/365,034).
