Inserting germanium nitride thin films between Sb-Te (for super-resolution readout) and ZnS-SiO 2 layers was effective to improve super-resolution readout durability of a super-RENS disc using a PtO x -SiO 2 write-once recording layer. Waveform of 97-nm (that is below the resolution limit of the optics used) and 340-nm combined marks scarcely changed even after 50,000 times readout. CNR of 100 nm marks was stable (within 3 dB decrease) after 268,000 times readout.

“…By combining a 3 cm diameter disc and a micro pickup with Blu-ray optics data capacities in the order of 1 GB have already been demonstrated (Van der Aa et al 2003). Capacities in the order of 5 GB may be achieved in the near future by using near-field optics (Davies et al 2007) or discs with a non-linear layer structure that is called super-resolution near-field structure (Bae et al 2007). There are two popular approaches to reduce the size of optical drives.…”

Small form factor optical drives for mobile application require high performance actuators that satisfy tight geometrical size requirements. We have designed a swing arm type actuator that allows the integration of a complete miniaturized optical pickup unit on the actuator. The performance of the actuator has been simulated by the FEM method and is compared with experimental results. Finally the manufactured actuator was used to read out a Blu-ray ROM disc.
