“…When current is applied to the coil, the collimator can move back and forth to correct spherical aberration. Typical methods to derive the spherical aberrations signals reported in literatures include: using a holographic optical element called polarizing diffraction grating (PDG) [11], [12], and using a photo-detector split into inner segments and external segments.…”

This paper presents the system design of double-layer Blu-ray Disc recorders built in Philips Research Laboratory. The system architecture, new components, and the advanced signal processing are addressed. The experimental results show that writing HDTV programs to double-layer Blu-ray Discs and reading them back have been achieved. In addition, this paper demonstrates that discs with higher density and higher capacity are possible with the advanced technologies developed.

We have applied the blue-violet laser in developing several technologies for the next-generation digital versatile disk (DVD). We are convinced that four items, i.e., large capacity, high data-transfer-rate, cyclability, and portability, are equally important. We have set targets for capacity and data-transfer-rate. Separate development processes have been carried out in the fields of optical heads, systems (servo-mechanisms, read/write channel and signal processing) and basic subjects and combined the results to achieve our targets. Basic subjects that cross these technical fields and have previously been neglected were studied to find solutions to new problems that arise with next-generation requirements.
