    Abstract: Methods and apparatus for recording and retrieval of optically readable data employ a recording medium (100) which comprises an optically active material (108) able to induce a change in properties of the medium in the presence of optical radiation having a first characteristic, such as a first optical frequency, and wherein the change in properties can be inhibited by optical radiation having a second characteristic, such as a second optical frequency. During recording, a region of the recording medium (100) is irradiated with a first beam (506) of optical radiation having the first characteristic, the beam having a sufficient intensity within a central portion of the irradiated region and being of sufficient duration to cause an optically induced change in properties of the recording medium. Simultaneously, the region of the recording medium (100) is irradiated with a second beam (508) of optical radiation having the second characteristic, the second beam having a local intensity minimum within the central portion of the irradiated region, and a local intensity maximum in at least one portion of the irradiated region adjacent to the central portion which is sufficient to inhibit the optically induced change in properties of the recording medium. A similar method is employed for retrieval, however the intensity of the first beam (506) is reduced to prevent changes in material properties within the recording medium (100).

    Abstract: An angle grind coating apparatus and method for providing a coating onto materials is described. The angle grind coating apparatus comprising workpiece holder (102) assembled for holding tool material (104) and is assembled over base (106) provided over a fixture (108). The workpiece holder (102) has a spring assembly (110) to apply an upward thrust force to the tool material (104) and a grinding wheel (114) is mounted perpendicular to the workpiece holder (102) to enable grinding of the tool material (104) fixed in front and just below the grinding wheel (114) to align the fixture (108) with the grinding wheel (114). The angle grind coating apparatus comprises an angle grinder (116) to enable rotation of the grinding wheel (114) over the tool material (104) at a predefined Rotations Per Minute (RPM), such that rotation of the grinding wheel (114) generates a stream of swarf particles (118) from the workpiece/tool material 104 and are deposited over a target surface fixed (120) at a pre-set standoff distance from the angle grind coating apparatus.
