ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an optical disk, more particularly to an optical disk that includes a disk body and a cap body, both of which are adapted to be printed thereon.
2. Description of the Related Art
FIGS. 1 and 2
illustrate two conventional optical disks
4
,
5
. The conventional optical disk
4
is circular, whereas the conventional optical disk
5
is rectangular. Each of the conventional optical disks
4
,
5
has a surface adapted to be printed thereon. Each of the conventional optical disks
4
,
5
further has a central through hole

for extension of a rotary driving shaft (not shown) of an optical disk reader.
Due to the presence of the through holes
40
,
50
, the area of the conventional optical disks
4
,
5
that can be printed is relatively small, and the picture that is printed on the surface of the optical disks

is not complete.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide an optical disk that includes a disk body and a cap body, both of which are adapted to be printed thereon to result in a larger printable area.
According to the present invention, the disk body of an optical disk has a first surface adapted to be printed thereon, a second surface opposite to the first surface and adapted to store optical data, and a central through hole extending from the first surface through the second surface and confined by an annular hole surface. The disk body further has a cap seat flange that extends radially and inwardly from the hole surface and that is formed with a plurality of mounting holes therethrough.
The cap body of the optical disk includes a cap plate disposed in the through hole. The cap plate has a top side adapted to be printed thereon, a bottom side, and a peripheral portion on top of the cap seat flange. The cap body further includes a plurality of hooking arms that extend from the peripheral portion at the bottom side and that extend slidably through the mounting holes.
