Abstract: A stamper protector is disclosed which is comprised of a recording cover and a center cover. The recording cover is made of a laminated material which has a tough outer layer and a resilient soft inner layer. The recording cover is cut in the form of an annular ring of a size such that it will cover the entire recorded area of the stamper from the outer molding land to the unrecorded center portion of the stamper. The center cover is cut to a size which will cover the entire center of the recording cover when it is adhered to the outer layer of the recording cover.

Abstract: A video disc caddy comprises a jacket and a record retaining spine. The jacket includes a U-shaped rigid frame having a peripheral edge wall and an intermediate flange extending inwardly from the edge wall at substantially right angles thereto. The intermediate flange in conjunction with the interior surfaces of the edge wall defines a pair of channels. A pair of inexpensive panels, made from sheet stock, are securely mounted in the respective channels to define a record enclosing cavity.

Abstract: The invention concerns an improvement of sleeves such as sleeves for gramophone records. The sleeves consist of a front and a back panel connected at one edge by a connecting strip, which is in the blank arranged between the two panels, and two other connecting strips extending from one panel and glued to edge zones of the other panel by means of gluing flaps. Gluing flaps and edge zones which are to be glued together in overlapping position are reduced in their thickness so that the seam is as thick as the material of the back panel. Reduction in thickness is achieved preferably by milling off a layer from the cardboard material of the gluing flaps from their outer surfaces as well as of the edge zones at their inner surfaces. The sleeves have panels of equal thickness so that the gramophone records are supported all around their edges and in their middle parts without causing bending when stacked.

Abstract: A cover for a video record has a generally unbroken rectangular perimeter. A record player has permanent magnets that cooperate with paramagnetic inserts in the record cover to open the cover for loading and unloading a recording disk. The player has a clamp mechanism that enters the opened cover to clamp the disk for these operations.

Abstract: A disc record caddy comprises a jacket having an edge opening in communication with a record enclosing cavity, and a record retaining spine subject to insertion into the jacket. The spine defines a first portion forming a closure for the edge opening, and a further portion having a perimetrical wall defining an opening in which the enclosed record is received. A portion of the perimetrical wall disposed between the enclosed record and the closure portion of the spine defines a molded-in recess for selectively receiving a peripheral portion of the enclosed record.

Abstract: An antistatic phonograph record envelope for storing records in a cardboard jacket is made from extruded plastic film having a thickness between about 1 and 6 mils with an antistatic agent extruded within the film. Layers of the plastic film have one or more seams providing a closed end and sides while an open end of the envelope has an elongated slit through which the record is inserted into the envelope for storage and pulled out of the envelope for use. The antistatic agent in the plastic film layers prevents the buildup of static electricity on the record as it is inserted into and pulled out of the envelope and also dissipates any accumulated static electricity on the record during storage within the envelope. At the open end, the plastic layers preferably have cooperable projections that are snapped into engagement with each other to provide a seal for the envelope.

Abstract: A package is provided for phonograph records in which four small-diameter records are packaged in a sleeve having the outside dimensions corresponding to those of a sleeve for a large diameter record. The package is comprised of a sleeve having a cruciform separator mounted between the front and rear panels of the sleeve. The separator defines four pockets, one for each of four small-size records packaged in the sleeve. The sleeve typically is square in outline and the pockets are located in slightly overlapping relation at each corner quadrant of the sleeve, access being had through opposite open side edges of the sleeve.

Abstract: A record caddy, suitable for use with a video disc player, includes a sleeve and a record retaining spine removably located therein. Disposed on the spine are latch members for releasably locking the spine to the sleeve. Latch defeat fingers, disposed in the player, are wedged between the respective spine latch fingers and interior portions of the sleeve during a caddy arrival at a fully inserted position in the player, so that the spine latch fingers are deflected in a manner freeing the spine from the sleeve. The latch defeat fingers carry extensions which are subject to reception in pockets disposed on the spine latch fingers to lock the spine to the player when the caddy is fully inserted into the player, whereby the spine, freed from the sleeve and secured to the player, is removed from the sleeve and retained in the player resting on a platform along with an associated record during subsequent sleeve withdrawal.

Abstract: A record caddy, suitable for use with a video disc player, comprises a jacket and a record retaining spine removably located therein. Disposed on the spine are lateral latch fingers for releasably locking the spine to the jacket. The spine has a pair of slots into which a locating member disposed in the player is received to assure accurate location of the spine in the player. A pair of cutouts are disposed in the spine in which gripper members of the record extracting mechanism are received to lock the spine to the player so that the record/spine assembly is retained in the player during subsequent jacket withdrawal.

Abstract: A system is provided for authenticating products having a paperboard cover or package, such as a record sold in a paperboard record jacket, a tape sold in a paperboard tape box, or a book having a paperboard cover. The cover or package includes a plurality of walls wherein at least one of the walls includes a sheet of paperboard material, with the sheet being formed from a plurality of plies of paperboard material. In addition, at least one of the internal plies of the paperboard sheet is coded, such as by color or phosphorescent material, either continuous or in stripes, to act as an indicator. The coded ply is visible along the edge of the wall of the cover or package to provide a system for authenticating the product.

Abstract: A phonograph record album with an outer sheet having informational material printed thereon. The sheet is folded over the base jacket so that it covers both sides of the jacket. This is done in an automatic machine which applies half the sheet to one side and then reverses itself to apply half to the other side.

Abstract: A playing record cover which when in the open position assumes a pyramid shape for combined use as a turntable dust cover and storage rack for records.

Abstract: A video disc player utilizable with a flexible foil-type information carrier disc adapted to be rotated at its center at a relatively high speed while hovering on a rotation-induced air cushion above a stationary platform. The video disc player has a table structure including the platform and a disc receiving chamber designed such that, even if the video disc is inserted thereinto together with a disc envelope accommodating the video disc therein, the disc is drawn out of the envelope and subsequently fed onto the platform and that the video disc, which has been resting on the platform, can be fed into the envelope as the empty envelope is inserted into the disc receiving chamber.

Abstract: An assembly comprised of a flexible, magnetic recording disk and a jacket or envelope which houses the disk in a manner such that the disk can rotate in the jacket under the influence of a conventional disk drive. The jacket has a notch at one corner thereof to provide a write enable function for the assembly when used with the disk drive. A rigid member is provided adjacent to the notch to close the opening formed thereby between the two sides of the jacket and to reinforce the corner to prevent structural damage to the jacket when used with the disk drive. The jacket is formed from an initially flat sheet of material and, except for the aforesaid rigid member, there is no structure between the outer periphery of the disk and the adjacent margin of the jacket.
