Indication of optically writable optical disc surface incident to laser

摘要

A mass-storage device according to an embodiment of the invention is disclosed that includes a laser and an indication mechanism. The laser at least optically writes to an optically writable surface of an optical disc incident to the laser. The indication mechanism indicates whether the optically writable surface incident to the laser is an optically writable label surface or an optically writable data surface of the optical disc.
