Abstract

We have recorded 1TeraByte of data in 200 layers in the volume of one DVD-like two-photon 3D disks. Each layer contains 5GBytes of data, equal to single layer DVD capacity. The results obtained with our high-performance 1.0NA objective lens show a full disk recording of 1 TByte within a standard optical disk form factor of 120mm × 1.2mm thick utilizing our very stable and efficient materials. Very high sensitivity materials are used to store information with bit energies as low as 250pJ/bit. Materials sensitive at 405nm are been tested by recording with 405nm Nichia laser diodes. Results show that bit dimensions are further reduced enabling future recordings at 5TByte disk capacities by recording 25GBytes/layer, the equivalent of a Blu-ray disk capacity per layer.
