Abstract
A method and a recording device capable of selecting a preferred write strategy from a plurality of write strategies for an optical disc. The optical disc contains a characteristic value. The method includes: reading the characteristic value from the optical disc; selecting a first write strategy from the write strategies to be an active test write strategy according to the characteristic value of the optical disc; writing a test pattern onto the optical disc according to the active test write strategy; and reading the written test pattern from the optical disc, checking if the written test pattern satisfies a corresponding criterion, and utilizing the active test write strategy to be the preferred write strategy if the written test pattern satisfies the corresponding criterion.
