Abstract: A write-protect ring for protecting an optical disk from being written upon is disclosed. The write-protect ring includes an adhesive portion and a non-adhesive portion so that the non-adhesive portion is nearer data regions of the optical disk, thereby preventing the adhesive from interfering with the data on the optical disk. The write-protect ring may also include permanent adhesive which prevents the write-protect ring from being removed from the optical disk without damage to the optical disk.

Abstract: The present invention is a device and method to install a compact disk media write-protect ring 104. The device 200 positions the write-protect ring 104 so that it is aligned with the center hole of the disk 100. Aligning the write-protect ring 104 with the center of the disk 100 ensures that the ring is in the correct location, thereby enabling the write protect function. The device 200 includes a hub 202 upon which the center hole of the disk 100 is pressed, thereby securing the disk to the device. The device 200 also includes a support 206 that surrounds the hub 202 and is connected to the hub so that it may move axially along the hub. This support 206 serves as a shelf for the write-protecting 104 and a press to assure good contact between the disk and the adhesive of the write-protect ring. In operation the write-protect ring 104 is positioned on the support 206 with the adhesive exposed and facing upwards away built the support. The disk 100 is then placed on the hub 202 with its data side down.
