Abstract
A system and method for reading and writing in a multilevel optical data system is disclosed. The system provides control signals for timing acquisition, level calibration, DC control, AGC, equalizer training and data synchronization. The user data is ECC protected and optionally convolutionally encoded before being combined with the control signals in an information block. The multilevel information block can be written to an optical disc as a series of multilevel marks. The optical disc may also contain an Address in Pregroove signal (AIP) to facilitate synchronization during writing of an information block. The AIP signal has an integer number of address frames per information block.
