Patent ID: 8050165

Claim:
A recording apparatus which records data on a holographic memory comprising: an interface circuit which inputs data; a modulating circuit which modulates the data inputted through the interface circuit onto a light beam; and a recording module which multiplex records data, using the modulated light beam from the modulating circuit, on a holographic memory in units of a predetermined volume; wherein the recording apparatus can load a disc which has a holographic memory area and a bit-by-bit recording track, and wherein a first part of the data which is able to be multiplex recorded every predetermined volume is recorded on the holographic memory and is cured, a second part of the data which is not able to be multiplex recorded every predetermined volume is not cured at a timing when the first part is cured, and the second part of the data is recorded on the bit-by-bit recording track at a timing when the first part is cured.
