Abstract
Using swept-carrier frequency-selective optical data storage techniques to record multikilobit-long data streams at single spatial locations, we have achieved an areal storage density of 8 Gbits/in.2 and a density–input/output bandwidth product of 1.5 × 1017 bits/(in.2 s). The latter quantity is among the highest demonstrated in the context of nonparallelized two-dimensional optical or magnetic recording systems. Extrapolation of the present results to full material utilization suggests an achievable storage density of the order of 100 Gbits/in.2.Keywords
