ABSTRACT:
A disc jacket, especially for a photo-magnetic disk which records, reproduces and erases information, has a single opening configured to receive both a recording head and a central spindle. The opening extends along the whole radius of the disk to enable effective use of a larger area of the disc. The opening is opened and closed by a pair of shutter blades which automatically open when the disk jacket is inserted in an information recording and reproducing apparatus.
