Abstract

1Tbyte of data has been recorded in 200 layers inside the volume of one of our two-photon 3D disks. Each layer contains 5Gb of data similar to the capacity of a single layer DVD. The results obtained with our high-performance 1.0 numerical aperture (NA) objective lens show a full disk recording of 1Tbyte within a standard optical disk form factor 120mm×1.2mm thick utilizing our very stable and efficient materials. Very high sensitivity materials are recorded with bit energies as low as 250pJ/bit. Materials sensitive at 405nm are experimentally tested by recording with a 405nm Nichia laser diode. Results show that bit dimensions are further reduced, which enables future recordings of 5Tbyte disk capacities by recording 25Gb/layer, the equivalent of a Blu-ray disk capacity per layer.
