Lite-On Technology Assigned Two Patents

Optical disc and method for judging whether optical disc is placed reversely
Lite-On Technology Corporation, Taipei, Taiwan, has been assigned a patent (10,115,426) developed by Ho, Yu-Ta, and Chien, Chou-Chien, Taipei, Taiwan, for “optical disc and method for judging whether optical disc is placed reversely.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method is provided for judging whether a double-sided optical disc is placed reversely. Firstly, the disc is loaded. Then, a first optical pickup head emits a first laser beam to a first specified area of the disc and receives a first reflected laser beam. A second optical pickup head emits a second laser beam to a second specified area of the disc and receives a second reflected laser beam. If the first reflected laser beam generates an alternate brightness and darkness change and the second reflected laser beam does not generate the alternate brightness and darkness change, the disc is not placed reversely. If the first reflected laser beam does not generate the alternate brightness and darkness change and the second reflected laser beam generates the alternate brightness and darkness change, the disc is placed reversely.”

The patent application was filed on March 27, 2018 (15/936,949).

Solid state storage device and read control
Lite-On Electronics (Guangzhou) Ltd., Guangzhou, China, and Lite-On Technology Corporation, Taipei, Taiwan, has been assigned a patent (10,115,468) developed by Zeng, Shih-Jia, and Fu, Jen-Chien, Taipei, Taiwan, for “solid state storage device and read control method thereof.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A solid state storage device includes a non-volatile memory and a controlling circuit. In a first read retry process, the controlling circuit judges whether an information corresponding to a first block of the non-volatile memory is recorded in the cache table. If the information is not recorded in the cache table, the controlling circuit sequentially provides plural predetermined retry read voltage sets to the non-volatile memory according to a sequence of the plural predetermined retry read voltage sets in the retry table and performs a read retry operation. If a read data of the first block is successfully decoded through the read retry operation according to a first predetermined retry read voltage set of the plural predetermined retry read voltage sets in the retry table, the controlling circuit records the first predetermined retry read voltage set into the cache table.”

The patent application was filed on April 5, 2017 (15/479,315).
