摘要 |
An optical data carrier has a pair of spiral tracks of opposite hand that may be read either sequentially or simultaneously. When read simultaneously, the information is recorded at a uniform spatial density and demodulated into a common data stream. The heads reading the tracks are equidistant from a median radius and move along the carrier at a constant radial rate to provide a substantially uniform combined data rate. |
