Abstract: A method is provided for rebuilding a flash translation layer table of a solid state drive. The superblock includes plural superpages. Each of the plural superpages includes plural physical pages. The method includes steps of confirming if the flash translation layer table is lost or not after the solid state drive is powered on; if the flash translation layer table is lost, starting a superblock scanning method for determining a status of the superblock; and rebuilding the flash translation table according to the status of the superblock. The superblock scanning method includes steps of reading contents of a first physical page and a last physical page of a last superpage in the superblock, and determining a status of the superblock according to the contents of the first physical page and the last physical page.

Abstract: A data management method for a solid state storage device is provided. The solid state storage device includes a memory cell array. The memory cell array is divided into first-portion logical blocks and second-portion logical blocks. The data management method includes the following steps. Firstly, a write data of plural pages from a host are stored into a first logical block of the first-portion logical blocks. Then, a specified operation is performed on the write data of the plural pages, so that a parity data is acquired. Then, the parity data is stored into a second logical block of the second-portion logical blocks.

Abstract: A data programming method for a solid state drive is provided. The solid state drive has a flash memory with plural blocks. If a garbage collection is determined to be performed, a first open block is selected from the plural blocks of the flash memory for storing a moved valid data corresponding to the garbage collection. Then, the moved valid data corresponding to the garbage collection is programmed into the first open block. A second open block is selected from the plural blocks of the flash memory for storing a write data from a host.

Abstract: A superblock scanning method is provided for scanning a superblock of a solid state drive. The superblock includes plural superpages.

Abstract: A projection touch system configured for detecting a position of a touch object and a projection touch method thereof are provided. The projection touch system includes an invisible light source, a projection panel and a light detector. The projection panel includes a transparent plate and a fluorescent film. An invisible light beam emitted by the invisible light source scans back and forth on the projection panel. A first fluorescent light beam and a second fluorescent light beam are emitted from the fluorescent film excited by the invisible light beam. When the touch object is touched to the projection panel, a portion of the invisible light beam is reflected to the fluorescent film, and the second fluorescent light beam is emitted. The light detector detects the second fluorescent light beam relative to the first fluorescent light beam by an intensity level to determine the position of touch object.

Abstract: The invention is to provide a method for determining an adaptive writing strategy and for controlling, according to the adaptive writing strategy, an optical information recording apparatus to record data onto an optical information recording medium. According to a preferred embodiment of the invention, first, a calibration area of the optical information recording medium is judged whether it is full or not. If the result of judgment is YES, at least one condition data associated with the optical information recording apparatus is accessed, and a plurality of OPC (optimum power calibration) data sets previously recorded on the optical information recording medium are retrieved. Then, based on the at least one condition data, one of the retrieved OPC data sets is selected. The adaptive writing strategy is determined in accordance with the selected OPC data set.

Abstract: A method for recording data on an unformatted optical disk, wherein the optical disk has a lead-in zone and a data zone, includes: writing a storage data into the data zone according to a predetermined laser power before the lead-in zone records data; and beginning to write disk information into the lead-in zone when the storage data is completely recorded in the data zone.
