Abstract： |
It is multi-channel parallel writing method of photochromic multiwavelength laser storage and belongs to the field of optical storing technique. This method use binary encoder to transfer the single-channel one-dimensional user data to multi-channel binary data, and make the enciphered multiple-line binary data array meet the (d£¬k) run-length limitation. Every line of this binary data array meet d constraint, and meet k constraint just under the unite mode. Then input the data of every line of this binary data array to one data channel, and every data channel control the writing operation of one laser device, so to realize data parallel writing of multiwavelength laser storage. |
