Abstract

We propose a novel multi-pickup and multi-disk drive, in which multiple optical disks are mounted on a spindle at a equal spacing and multiple optical pickups, whose quantity is equal to that of the data surfaces of the optical disks, simultaneously read or write data in parallel. The key part of the drive is its servo-control system, which controls these optical pickups in parallel to implement the focusing servo-control and the tracking servo-control of each optical pickup in real-time in order to ensure the correct data read or write. The drive is important solution to offer super-large-capacity and quick-data-access information storage.
