Fast Optical Compact Disk Drive

New dimension Research and Instruments proposed to develop an innovative optical CD drive, which allows simultaneously reading sixty-four bits at any given time. Different from any commercial available optical CD reader and writer (only one laser and one detector for reading one bit at any given time), there are at least 64 laser and detector pairs in our proposed the CD driver, which are built at same chip. It dramatically increases data processing time. The goal of the proposed phase I program is to demonstrate the feasibility to design and make a optical CD driver with a novel LDA chip. The major issue that must be resolved in the phase I program is to demonstrate the feasibility of the proposed parallel read and write. The technical issues that must be resolved in the Phase I program are: 1. Determine optimum configuration for parallel read 32 bits from a rotating disk. 2. Determine optical parameters of VCSEL laser power, mode, f/number, and detector quantum efficiency, the laser and detector pitch for CD optical driver 3. Determine the optical parameters for focusing lens, tracking system Determine the optical disk formats for the parallel reading and writing.
