  • Patent number: 11254559
    Abstract: This invention describes the structure and function of an integrated multi-sensing system. Integrated systems described herein may be configured to form a microphone, pressure sensor, gas sensor, multi-axis gyroscope or accelerometer. The sensor uses a variety of different Field Effect Transistor technologies (horizontal, vertical, Si nanowire, CNT, SiC and III-V semiconductors) in conjunction with MEMS based structures such as cantilevers, membranes and proof masses integrated into silicon substrates. It also describes a configurable method for tuning the integrated system to specific resonance frequency using electronic design.

  • Patent number: 10553241
    Abstract: A method and system provides a near-field transducer (NFT) for a heat assisted magnetic recording (HAMR) transducer. The method and system include forming the disk of the NFT and forming the pin of the NFT. The disk is formed from a first material. The pin is formed from a second material different from the first material. The pin contacts the disk. At least a portion of the pin is between the disk and an air-bearing surface (ABS) location.

  • Patent number: 9449625
    Abstract: A heat assisted magnetic recording (HAMR) writer is described. The HAMR writer is coupled with a laser and has an air-bearing surface (ABS) that resides near a media during use. The HAMR writer includes a waveguide, a near-field transducer (NFT), a main pole, coil(s) and at least one of a first and a second diffusion barrier layer. The waveguide is optically coupled with the laser and directs energy from the laser toward the ABS. The NFT is optically coupled with the waveguide and focuses the energy onto a region of the media. The main pole writes to the region of the media. The main pole has a top, a bottom, and a plurality of sides. The first diffusion barrier layer is between at least the NFT and the bottom of the pole. The second diffusion barrier layer is adjacent to the plurality of sides of the main pole.
