Abstract
The present invention is a two-part optical disk with a nested, centrally positioned removable disk in the original configuration the disks comprise two disks removably joined together so as to enable both disks to be readable with a computer disk drive. The two-part optical disk is further configured so as to be separable into independent disks. After separation of the two disks, only data on the formerly nested inner optical disk continues to be accessible by a computer disk drive. Data on the formerly surrounding outer disk is no longer accessible by a computer disk drive The two-part optical disk has large data storage capability but with separation offers all the advantages of the small disk format: convenient storability, portability and support functionality.
Claims3
A two-part optical disk comprising:
- an outer disk storing first data;
- surrounding and removably joined to a smaller nested disk;
- storing second data within said disk with disks separable.
A selectively removable two-part optical disk comprising:
- a first outer disk storing first data;
- a second disk removably joined to the first disk, storing second data thereon and;
- a sprocket hole in said disk for proper engagement with a computer disk drive enabling both first and second data readable by a computer optical disk drive while the disks are joined together;
- and the data readable on the second disk when the disks are separated.
A two-part optical disk comprising;
- an optical disk removably joined nested disk and selectively separable from an outer optical disk;
- and, after separation from the outer disk, is the only disk having the sprocket hole for engaging a disk drive for continuing data readabity by a computer.
