IPC: G11B7/007
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To enhance the precision reliability and of a quality test by reproducing test data positioned at the peripheral outer side of a main information storage area and judging the quality of an optical disk based on the reproduced test signal. SOLUTION: A comparator 35 compares the bit pattern drawn from a pit pattern signal with a reference bit pattern on the basis of pit-to-pit → to sum the total quantity of recognized data and moreover, compares the total recognized quantity of these data with threshold values of predetermined recognition data stored in a memory 34. Thus result is outputted to a controller 36. Moreover, threshold valves of recognition data concerning respective reproduction modes of periodic and partial selections are successively stored in the memory 34 similarly with the testing of the pit pattern. When the total quantity of recognized data exceeds the threshold values of the recognition data, a controller 36 judges that an optical disk 31-1 has excellent quality and, in other cases, the controller 36 judges that the disk has insufficient quality.
