TRANSMISSION METHOD FOR DIGITAL DATA

摘要

PROBLEM TO BE SOLVED: To reproduce information data with high accuracy. SOLUTION: Digital data are contained in a sector consisting of plural synchronization frames and sent sequentially. The synchronization frame consists of a synchronizing signal and a run length limited code satisfying limitation of a minimum run length and a maximum run length and the synchronizing signal includes a synchronization pattern consisting of a bit pattern with a run length longer than the maximum run length by 3T and an additional bit pattern with a run length longer than the minimum run length allocated before and after it. Furthermore, the synchronizing signal includes a specific code representing a position in the sector and for DC control available.
