A package for a holographic storage media (10) is provided that utilizes a slide tray (43) for containing a plurality of slides (102). Each of the slides (102) is comprised of an opaque casing (110), which is operable to hold a sandwich structure (120). The sandwich structure (120) has a gripping mechanism (122) disposed on the edge thereof for allowing the structure (120) to be reciprocated within the jacket (110) for extraction thereof and reinsertion thereof. A gripping arm (156) is operable to attach to a gripping member (124) on a gripping mechanism (122) attached to the slide (102) to extract the slide (102) and place it into a holder (148). The holder (148) is then operable to receive the slide (102) and dispose it in a holographic storage system. The slide (102) can then be written to by interfering a data beam and a reference beam in a predetermined storage location (54) and then the slide again placed into the jacket (110).

Packaging system for holographic storage media

A ribbon cartridge (10) is attached to a carrier (1) of a printing device such that it is tiltable along an axis that is parallel to the print line to drop the ribbon such that the print line is visible. That part of cartridge (10) which is opposite of the ribbon exposing part and on the other side of tilting axis (18) is on its bottom provided with a ribbon advance knob (8). Into this knob (8) two essentially upright standing walls and inclined ramps (11) are molded. The ribbon feed device (6), provided on carrier (1), has a blade (5) or noses (17) which cooperate with slot-forming walls (12) of knob (8). In ribbon drive direction (14) cartridge (10) automatically drops into coupling interconnection for ribbon feed. Upon turning ribbon feed device (6) in reverse direction (16) blade (5) or noses (17) slide up ramp (11) and lift the rear part and drop the front part of the cartridge (10) so that the print line is rendered visible.
