Abstract
A system for page-based optical data storage includes a sensor array positioned to track a data page when the data page is optically read from or recorded to a storage medium. A servo mechanism is used to position the sensor array. A plurality of alignment points are defined relative to the photodetector pixel array. An alignment arrangement is located at each alignment point. The sensor array further includes servo-feedback signal generation logic operative to drive the servo mechanism based on error signals from the alignment arrangements, thereby aligning the two-dimensional photodetector array with respect to the two-dimensional data page.
