Removable cover for video disk and a video disk and player system for use with a disk having a removable cover.

摘要

A cover (14) for a recording disk (12) having non-magnetic recordings thereon is formed from two shoets of non-magnetisable material superimposed and joined together to form a container with an opening for receiving and covering a recording disk. An element of magnetisable material is attached to one sheet adjacent to the opening for use in enlarging the opening.
<??>The cover and recording disk are for use in a record player having a playing station including reading means arranged to read the non-magnetic recordings on the disk. The disk, in its cover, is inserted into the player and when the disk reaches the playing station a permanent magnet (49) attracts the magnetisable element in the cover and enlarges the opening in the cover. A clamp operates within the enlarged opening to hold the disk in position in the playing station while the cover is removed.
<??>When the cover is reinserted into the player to cover the disk, a second permanent magnet (63) attracts the magnetisable element and opens up the cover to allow it to be inserted over the disk.
