Title: Servo address device and positioning method for read, write and seek operations in direct access storage device
Inventor: RICHIYAADO GURIINBAAGU
IPC: G11B21/10
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent an error of a read position by generating a positioning error correcting code(ECC) checking byte by an ECC generator, loading a servo address into the ECC generator in advance and Judging the write position. SOLUTION: The servo address is written in a servo burst, and is loaded into the ECC generator, so that the write positioning ECC checking byte is generated and stored. Subsequently, a subservo address is written in the servo burst, and is read during track seeking to position a converter head. At the time of writing data, the servo address and the positioning ECC checking byte are read, and the write position is judged by the ECC generator and entered together with a logical block address(LBA). By loading the servo address and the LBA into the ECC generator in advance at the read time, whether the write position is correct or not is judged, and a data error is detected, and simultaneously the read operation in a wrong position is prevented.

Filed: 1992-11-13
Abstract: PURPOSE:To provide a method for extracting polysaccharides in which the polysaccharides contained not only in a wet algal body but also in a culture solution can be extracted at a low cost according to simple operation without causing the pigmentation. CONSTITUTION:This method for extracting polysaccharides is characterized by allowing a culture solution of an alga in a sterile state to stand until a pigment in the culture solution fades while irradiating the culture solution with light and then extracting the polysaccharides in extracting the polysaccharides from the culture solution of the alga. Thereby, the light-colored polysaccharides can be obtained according to simple operation. The washing operation for the purpose of removing pigments after recovering the polysaccharides is not required. The operation can be simplified and the amount of the washing solvent can be reduced.
