Methods and apparatus for rendering an optically encoded medium unreadable
Abstract
The invention claims with internal optical to be to read method and device for medium (20) can be reading. Method for comprising steps: (a) is provided with a groove to the medium with mixing the information of locating reflection surface of the optical movable mechanism; (b) leg the medium a light radiation the read-out information,The exposing the walking object the working optical activating mechanism with (c). On the other handle; the optical movable mechanism for making the reading of light beam debunching, from the reduce the reading of light beam of enrolling information the reflection surface of. Arranged on the embodiment, method for the invention making the areal deformation layers; the reading of light beam deviation or non-rotationally stop correctly on the rail. Arranged on the embodiment, leg and upper part of the atmospheric environment, for carrying through oil or sublimation.

Method and apparatus for rendering an optically readable medium illegible
Methods and materials are described for rendering an optically readable media (20) unreadable. Method includes the steps: (a) equipped the medium (20) with an optically activated mechanism that degrades the reflectivity at the surface where the information is encoded, (b) exposing the medium (20) to optical radiation for reading the information, and, during the exposure step, (c ) initiate the optically activated mechanism. In a further aspect, the optically activated mechanism causes a deflection of the reading beam, thereby degrading the reflection of the reading beam from a surface where information is encoded. In another embodiment, the method deforms a surface of the layer resulting in a read beam deviation or in an inability to properly remain in the track.
