Abstract
A cassette having a drawer composed of a rigid support shelf and one or two data cards mounted to the shelf, and a rigid cassette case having sides defining a slot at a front end in the case for edgewise insertion of the drawer into the case. The drawer has at least one and preferably two holes at a front end therein coinciding with notches in sides of the case. A boss on either the drawer or the case is received by a groove in the other when the cassette is closed, thereby forming a detent. A second boss and groove may be provided on the opposite side. Each data card may be composed of a thin backing sheet adhered to the shelf, a strip of laser recording material disposed on the backing sheet and a transparent scratch-resistant plastic cover disposed over the strip.
