Patent number: 8009341Abstract: In a holographic information recording and reproducing apparatus, an optical fiber guides a reference beam toward a recording medium for holographic recording, and a precision rotator is turned, so that the reference beam is incident on the recording medium at different angles and interferes with a data-carrying signal beam to complete the recording of holographic information on the recording medium. To reproduce the holographic information, the optical fiber guides a reading beam, and the reading beam is incident on the recording medium at an angle the same as the reference beam for the recording to reproduce the holographic information stored on the recording medium. With the optical fiber and the precision rotator, a simplified light path system and a wide range of incident angles for the reference and reading beams may be achieved, and the transmissive, reflective, and 90-degree holographic storage techniques may be integrated in one single apparatus.Type: GrantFiled: October 29, 2008Date of Patent: August 30, 2011Assignees: CMC Magnetics Corporation, National Chiao Tung UniversityInventors: Mei Li Hsieh, Shiuan Huei Lin, Jui Hsin Wang, Ken Yuh Hsu, Don Yau Chiang

Publication number: 20090176048Abstract: A recording material of Ag1-xSbx (x=10.8˜25.5 at. %) films for WORM optical disk recording media is invented. The thermal analysis shows that the phase change temperature of AgSb film is between 250 and 270?. The optical property analysis shows that all the as deposited films have good optical absorption and high reflectivity. The X-ray Diffraction analysis shows that the as deposited film and the annealed film are kept at ??-AgSb crystalline phase. The TEM analysis shows that the grain size of the Ag80.9Sb19.1 film will grow after annealing. The dynamic test shows that the carrier-to-noise ratio (CNR) of the Ag80.9Sb19.1 optical disc is about 45 dB with ?=657 nm, NA=0.65 and a linear velocity of 3.5 m/s. These Ag1-xSbx films have good optical absorption, high reflectivity and good carrier-to-noise ratio. It can be used as the WORM optical disk recording film.Type: ApplicationFiled: April 10, 2008Publication date: July 9, 2009Applicant: CMC Magnetics CorporationInventors: Po-Cheng Kuo, Yen-Hsiang Fang, Po-Wei Chen, Wei-Chih Hsu, Don-Yau Chiang, Wei-Tai Tang, Shih-Hsien Ma
