ABSTRACT:
An optical disk player is provided with a casing or base which need not be substantially larger than a square inscribed by the circular perimeter of the compact disk which it plays by causing the optical pick-up to radially scan the disk along a path at a predetermined angle to the sides of the square, preferably at about 45.degree. thereto. At the outermost position of the pick-up, its object lens is centered at the outermost track on the disk, and a corner of the casing conveniently accommodates the portion of the pick-up which then necessarily extends outwardly beyond the outermost track.
