The method of inspecting disc information comprises a. outputting a standard command, for reading the disc structure of the disc; b. determining whether the reading was successful, if not, step c is performed; if yes, step d is performed; c. outputting a force read command, for reading the disc structure; d. receiving the disc structure; and e. outputting the corresponding disc information according to the disc structure. The invention can inspect various disc information of the optical disc, and the user database can be manually updated and expanded according to a user's will, thereby increasing the convenience of inspecting optical discs. | 11-13-2008 |
20080247294 | Data reading method - A data reading method used in a reading device for reading a holographic storage medium is provided. The holographic storage medium has several data areas. Each data area has several data pages, and each data page forms a data image that has at least one reserved block pattern on the reading device. The reserved block pattern of the data image corresponding to a first data page is searched within a first searching region to obtain a first pattern position. The reserved block pattern of the data image corresponding to a second data page is searched within a second searching region to obtain a second pattern position. A third searching position is then determined according to the first and second pattern positions. The reserved block pattern of the data image corresponding to a third data page is searched within a third searching region whose center is at the third searching position. | 10-09-2008 |
20080239908 | Method of detecting optical disk error information - A method of detecting optical disc error information on an optical disc, for applying in an optical disc drive, the method comprising: first, detecting whether the optical disc is blank, if not, perform the following: checking whether a seek error occurred, if yes, recording a seek error mark; while reading a data region, recording data error information, the data error information comprises an error count, and a corresponding data error location; finally, outputting the optical disk error information according to the data error information and the seek error mark. | 10-02-2008 |
