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.
Claims17
An apparatus for write protection of an optical disk, the optical disk having a power calibration area and a data area, comprising:
- a write-protect ring, that covers a power-calibration area of an optical disk when installed on the optical disk, wherein the write-protect ring has a first side with an adhesive portion and a non-adhesive portion, the first side of the write-protect ring contacting the optical disk when the write-protect ring is installed on the optical disk.
A method of write protection for a optical disk, the optical disk having a power calibration area and a data area, the method comprising:
- covering the power calibration area with a write-protect ring by adhering a portion of the write-protect ring to the optical disk.
An apparatus for write protection of an optical disk, the optical disk having a power calibration area and a data area, comprising:
- a write-protect ring, that covers a power-calibration area of an optical disk when installed on the optical disk, including an adhesive that allows the write-protect ring to be permanently be attached to the optical disk.
