ABSTRACT:
A write-protected data storage disk assembly comprises a disk carrier having a write-protect member movably mounted thereon for movement between two positions in which it enables and inhibits the writing/erase functions of a disk drive unit. During periods of non-use, the carrier is totally contained by a protective caddy. A write-protect indicator is movably mounted on the caddy, such indicator cooperating with the carrier's write-protect member to display the present write-protect status of the disk within.
