摘要： In a storage device, a bad-sector detecting unit detects a bad sector, and a process determining unit determines whether rescue process is performed for the bad sector. Upon determining to perform the rescue process, the process determining unit controls a damping ratio. A table-updating control unit records various information in an alternating-process control table, and a controller records and reproduces data with respect to a rescue sector based on the alternating-process control table.

摘要： An optical information recording medium having a plurality of grooves and a plurality of lands alternately formed, where each groove and each land function as recording tracks. The medium includes a first header region having a plurality of first phase pits respectively formed on extensions of the plurality of lands, and a second header region having a plurality of second phase pits respectively formed on extensions of the plurality of grooves. Each groove has an optical depth of about 3&lgr;/8, where &lgr; is the wavelength of a light beam to be used. Each first phase pit has an optical depth that is smaller than that of each groove. Each second phase pit has an optical depth that is substantially equal to that of each groove. The first header region and the second header region are shifted from each other along the extension of each groove.
