发明名称 OPTICAL DISC TEST METHOD AND OPTICAL DISC MEDIUM
摘要 <p>An optical disc verification method according to the present invention includes the steps of: writing data on first, second and third radial locations on an optical disc at a writing speed V1 and reading the data written there, thereby measuring read signal quality index values A, B and C, where the second radial location is inside of the first radial location and the third radial location is inside of the second radial location; writing data on the first and second radial locations at a writing speed V2, which is higher than V1, and reading the data written there, thereby measuring read signal quality index values D and E; and correcting the signal quality index value C with the difference between the signal quality index values B and E, thereby calculating a signal quality index value F that would be obtained if data is written on, and then read from, the third radial location at the speed V2.</p>
