Abstract

A thin film data storage carrier (e.g., a flexible thin film compact disc) is described. The thin film data storage carrier (e.g., 111 of FIG. 8 ) has a cruciform aperture ( 114 ) therein, which is defined in part by two pairs of opposed arcuate sides ( 117, 117 ′ and 120, 120 ′) and at least one tab ( 118 and 121 ). The tabs ( 118 and 121 ) each have a triangular shape. The thin film data storage carrier may be used as part of a digital data storage assembly ( 2 ) that includes a rigid support ( 29 ) having an aperture ( 30 ) therein. The assembly ( 2 ) further includes, a locking device ( 41 ) positioned at least partially around aperture ( 30 ) of rigid support ( 29 ). Locking device ( 41 ) includes at least one shelf ( 44, 47 ) extending out over a portion of the first surface ( 32 ) of rigid support ( 29 ). The shelf (e.g., 44 ) and a portion (e.g., 53 ) of the first surface ( 32 ) of rigid support ( 29 ) residing thereunder together define a tapered slot (e.g., 62 ), having an open end ( 59 ) and a closed end ( 56 ). Thin film data storage carrier (e.g., 111 ) is reversibly fixed to rigid support ( 29 ) by means of the tab (e.g., 118 and 121 ) of data storage carrier ( 111 ) being reversibly received within the tapered slot (e.g., 62 and 62 ′), when the thin film data storage carrier is in abutting relationship with the rigid support ( 29 ).

Claims (3)

1. A thin film data storage carrier having a cruciform aperture therein, said cruciform aperture being defined in part by two pairs of opposed arcuate sides and at least one tab, said tab having a triangular shape.

2. The thin film data storage carrier of claim 1 wherein said cruciform aperture is located in a central region of said thin film data storage carrier.

3. The thin film data storage carrier of claim 2 , wherein said thin film data storage carrier has two tabs, the tabs being positioned substantially 180° one from the other.
