Title:
HOLOGRAPHIC MULTIPLE RECORDING METHOD
Document Type and Number:
WIPO Patent Application WO/2005/050331
Kind Code:
A1
Abstract:
There is provided a holographic multiple recording method capable of obtaining a uniform remaining dynamic range in each recording area when holographic multiple recording is performed. The holographic multiple recording method includes: a step of arranging the recording spots RS in the X-axis direction without overlapping so as to form a first-stage recording sport row RX1; a step of recording a second-stage recording spot row RX2 consisting of recording spots RS not overlapping in the X-axis direction at the position of the Y-axis direction shift multiple recording; a step of repeating this so as to perform recording in all the recordable areas without performing X-axis direction shift multiple recording so as to form the Y-axis direction first multiple recording matrix TYX1; a step of forming a Y-axis direction second multiple recording spot matrix TYX2 with respect to the first-stage recording spot row RX1 recorded firstly; and a step of performing the X-axis direction shift multiple recording up to the Y-axis direction last multiple recording spot matrix TYXn.
