| Abstract: |
To protect a record, such as a video disc, from damage due to finger contact with the recorded area, a pair of finger holes are provided adjacent the centering aperture of the record. The record player and the package used for shipping or storing the record are each provided with a well for receiving the record. The spacing between a wall portion defining the edge of the well and the outer periphery of the record is such that the outer periphery of the record is not directly accessible, thereby constraining a user to handling the record by the finger holes. The player and the package are each provided with a finger cavity located underneath the finger holes regardless of the rotational orientation of the record when the record is in the well, in order to permit a sufficient penetration of the fingers so that the record may be firmly grasped for removal from the well.

What is claimed is:
1. A record protection system comprising:
- 1. a record having an outer periphery, a central unrecorded region, and a recorded region disposed between said outer periphery and said central unrecorded region; said central unrecorded region including finger receiving holes for facilitating the manual handling of said record;
- 2. record receiving means including a wall portion defining the edge of a well for removably receiving said record; and
- 3. a cover mounted for motion between a closed position and an open position relative to said record receiving means;
- the construction of said record protection system being such that said well is exposed to permit manual placement and removal of the record, when said cover is in said open position; and
- wherein the spacing between said wall portion and said outer periphery of said record, when in said well, is such that grasping of said outer periphery of said record directly with human fingers is precluded.
