Abstract
A compact media drive for use in personal computers has a media support and detector arm structure that ejects to extend external of the drive case at the insertion slot to receive corners of a unit of media during data operations. The arm(s) retract within the drive case or system case when no media is received. This allows a drive case to be proportioned with a drive hub for the media adjacent to the insertion slot to reduce the dimension there between from that for normal full disk insertion. The arm structure permits the drive to collect state information at the rear disk corners necessary to avoid incorrect data operations while a significant portion of the disk remains outside the insertion slot.
