Method for the distribution of data marks on a medium, and method and apparatus for the holographic recording and readout of data

摘要

The data is coded with coding which eliminates duplication of data above predetermined number of times. The size identifying array is determined such that coding data marks identical in size and state to identifying array data marks. Subsequently identifying arrays are filled with data marks having identical states. Independent claims are also included for the following: (a) Data read out method; (b) Holographic recording and read out method; (c) Holographic recording and read out apparatus.
