1. Introduction Huge capacity (over 100GB), random access and removable storage are now intensively investigated as holographic memory and multi layer recording, Here, we newly confirmed a stacked volumetric optical storage which is our new proposal named SVOD (Stacked Volumetric Optical Disks). As illustrated in Fig.1, a lot of nanoprinted thin optical disks are stacked in a small cartridge. From the cartridge, one thin optical disc can be operated using the conventional drive, which is removed through the compact auto-changer.

Three-dimensional pit selection (3DPS) is proposed for optical discs with the capacity of hundreds of gigabytes, where the super-resolution and multi-layer techniques are combined. In this method, a high transmittance of each layer is obtained by discrete opaque data pits made of a super-resolution material. The dual-layer disc was fabricated using a phase-change material as a pit material. The experimental data show that the super-resolution effect is obtained for both layers. The additional advantages and the future expandability are discussed

High-density multilayer optical disc storage was investigated by employing advanced signal processing methods such as adaptive equalization and adaptive partial-response maximum-likelihood (PRML) detection. Preliminary experiments, recording on single-layer and dual-layer Blu-ray discs (BD), indicate storage capability of 33.3 GB/layer with adaptive 5-tap PRML. A new signal qualification method, sequenced amplitude margin quasi-error estimation (SAMQES), was introduced for high-density multilayer recording, and possibility toward a total storage capacity of 200 GB was examined by using a six-layer BD-Recordable disc. Despite coherent interlayer crosstalk and lower signal-to-noise ratio, SAMQES showed moderate increase from those in single-layer recording.

It was found that the PTM (phase transition mastering) process usually use for mastering 25 GB blu-ray ROM discs had capability of producing a 65 GB ROM disc whose linear density and the track pitch were 77 nm/bit and 0.178 muum respectively. The jitter value of the 65 GB disc, measured with the assistance of the near field optics, was 5.5%

We propose a new wide-band laser noise cancel technique which is especially effective in Blu-ray Disc system because of its laser noise increasing compared with conventional optical disc systems. Laser noise cancellation method has already been available, but it is difficult to extend the noise suppression bandwidth for high-speed reading. So we examined the realization possibility of wide-band noise canceling and developed a new photo diode IC (PDIC) with noise cancel function based on our principle examinations. Big advantages in respect of the cost and space are expected to be obtained by adopting this technology.
