Patent
Optical waveguide and thermal assist magnetic recording head therewith
TL;DR: In this paper, the authors proposed an optical waveguide with a first and second triangular plate-like spot size converter members formed of the same material as a core material and being arranged and formed in a substantially symmetrical structure.
Patent
Surface plasmon antenna with propagation edge and near-field light generating element
Koji Shimazawa,Eiji Komura,Yasuhiro Ito,Seiichi Takayama,Satoshi Tomikawa,Daisuke Miyauchi,Kosuke Tanaka +6 more
TL;DR: In this paper, a surface plasmon antenna comprises an edge having a portion for coupling with a light in a surface-plasmon mode and extends from the portion to a near-field light generating end surface that emits near field light.
Patent
Thermally-Assisted Magnetic Recording Head with Light Detector in Element-Integration Surface
TL;DR: In this paper, a thermally assisted magnetic recording head is provided, in which the light source output can be adjusted according to its variation by environmental influences and over time, and a light detector for monitoring the light-source output, provided in the elementintegration surface and comprising a light-receiving surface covering an area directly above at least a portion of the optical system.
Patent
Light source unit for thermally-assisted magnetic recording capable of monitoring of light output
Koji Shimazawa,Yoshihiro Tsuchiya,Seiichi Takayama,Nobuyuki Mori,Yasuhiro Ito,Kosuke Tanaka,Osamu Shindo,Ryuji Fujii,Takashi Honda,Yoshitaka Sasaki +9 more
TL;DR: In this paper, a light source unit is attached to a sliding window to form a thermally assisted magnetic recording head, which enables constant feedback adjustment with high efficiency for the light output of the light source can be performed.
Patent
Spot size converter and thermal assist magnetic recording head therewith
TL;DR: In this paper, the authors proposed a spot size converter that is capable of shortening the waveguide length in the spot size converters and promoting a size reduction of the optical waveguide itself.
