ABSTRACT:
A record is removably subject to occupancy of a protective caddy comprising a jacket and a record retaining spine. The record is enclosed in the caddy such that a first side of the record is associated with a given side of the spine. To load a record into a player, such as a video disc player, an occupied caddy is inserted into an input slot provided in the player. A record extracting mechanism mounted in the player removes the retaining spine and the associated record from the jacket during jacket withdrawal subsequent to the occupied cover arrival at a fully inserted position in the player, whereby the record and the spine are retained within the player. A switch mounted in the player is subject to conditioning in a first state in response to insertion of the occupied cover with the given side of the spine facing upward, and is subject to conditioning in a second state in response to cover insertion with the given side facing downward. An indicator responsive to the state of the switich and disposed on the front instrument panel of the player provides an indication of the record side subject to playback.
