摘要
PURPOSE: A multi-level bit coding and decoding apparatus and method of a holographic digital data storage system are provided to modulate data pixels stored in a storage medium of the system to more than 3-level bits so as to improve recording density. CONSTITUTION: A multi-level bit coding apparatus of a holographic digital data storage system includes an input unit(102) and an N-level bit modulator(104). The input unit receives holographic digital page data. The N-level bit modulator modulates the page data to N bits and provides the modulated N-bit data to the holographic digital data storage system as coding data.
