Abstract
An optical drive writes information to an optical medium by obtaining a write strategy for the optical medium from a write strategy table embedded in the optical medium. A write module in the optical drive reads an optical drive identification code from the optical medium to select a write strategy associated with the optical drive. The write strategy of the embedded write strategy table that is identified for the optical drive is retrieved by the write module to write information to the optical medium with the optical drive using the identified write strategy. In one embodiment, a time stamp of the identified write strategy retrieved from the optical medium is compared with a time stamp of a write strategy already available to the optical drive to select the most recent write strategy for use by the optical drive. The write strategy table is embedded in the optical medium at manufacture of the optical medium, such as by stamping or burning the data into the optical material of the optical medium.
