EXAMPLE 1
[0214]The increased bit densities from short wave laser diodes are utilized to decrease duty cycle and corresponding power consumption. Assuming the present industry standard circular linear velocity read rate of 3.84 m / sec, the improved bit density from a short wave laser diode provides an increase in output bandwidth to 2.17 megabytes / second, an improvement of 1.57:1. Improved signal to noise also accommodate higher multiples n*X of linear velocity read rates and commensurate increases in output data bandwidth. The increased bandwidth of 2.17 megabyte per second results into a 17 megabit per second data stream, or essentially four times the bandwidth of a high resolution independent video stream. By buffering the overall operational duty cycle may be reduced to 25%. A buffer of 64 megabytes, 512 megabits, affords a buffer time of 2.13 minutes. A buffer of 640 megabytes provides a buffer time of 21.3 minutes. The increased bit densities from UV wave laser diodes may be si

The increased bandwidth of 2.17 megabyte per second results into a 17 megabit per second data stream, or essentially four high resolution independent video streams. Each stream may be partially or fully buffered to allow for seeks to multiple content streams. The increased bit densities from UV wave laser diodes are utilized to increase output bandwidth. Assuming the present industry standard circular linear velocity read rate of 3.84 m / sec, the improved bit density from a UV laser diode pro
