Development of an Optical Disc Recorder. (2002)
Kenney,G., Balas,C., Lou,D., Chan,A., Demetrakopoulos,T.
The mechanical parts of the recorder were designed and are in the first stages of assembly. The servo electronics were designed and fabricated. A coding study is under way for the design of the...
Development of an Optical Disc Recorder. (2002)
Kenney,George, Balas,C., Lou,D., Chan,A., Demetrakopoulos,T.
A program schedule with milestones is given for the materials development and recorder construction for an optical disc recorder. This schedule will be used, updated where necessary, on all...
Development of an Optical Disc Recorder. (2002)
Kenney,George, Lou,D., Wagner,J., Chan,A., Demetrakopoulos,T.
First testing of the recorder is underway. Some tracks were recorded on plastic discs coated with tellurium films. Laser machining of holes in static films of various materials reveals tellurium as...
Development of an Optical Disc Recorder. (2002)
Kenney,Geroge, Zernike,F., Lou,D., Goutmann,M., Milch,A.
The recorder was modified for limited operation at 3 rps. Refitting the new optical and digital subsystems into a deliverable system is now planned on a back-up sled and turntable. PMMA discs coated...
Development of an Optical Disc Recorder. (2002)
Kennedy,George, Zernike,F., Lou,D., Harper,Robert, Giebler,M.
Several air sandwich discs were fabricated and recordings made with them. Tellurium was chosen as the best material of those considered. Studies show that tellurium films are twice as sensitive as...
Development of an Optical Disc Recorder. (2002)
Kenney,George, Lou,D., Wagner,J., Zernike,F., McFarlane,R.
A laboratory-prototype, digital, optical disc recorder was developed with a storage capacity of 10 to the 10th power bits. Recording is done by laser machining of micron-sized pits in a thin...
Development of an Optical Disc Recorder. (2002)
Kenney,George, Zernike,F., Lou,D., Giebler,M., Milch,A.
Twenty tellurium air sandwiches were assembled in a new dedicated clean room. Preliminary tests of the sandwiches indicate acceptable characteristics for digital recording. The recorder prototype is...
Development of an Optical Disc Recorder. (2002)
Kenney,G., Zernike,F., Lou,D., Milch,A., Wagner,J.
A recorder test fixture was assembled from previously tested components. A single-color DRAW optical system was designed, built and tested. Life testing of tellurium and bismuth films has continued...
