Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical transmission type recording medium for a multilayered configuration type optical recording medium which can realize the recording capacity not possible heretofore.  <P>SOLUTION: The multilayered configuration type optical recording medium is formed by laminating a plurality of sets of recording layer constructs on a substrate formed with grooves of a width 0.10 to 0.46 μm and a depth 0.01 to 0.04 μm at a pitch 0.28 to 0.50 μm and performs recording or reproducing to the plurality of the sets of the recording layer constructs by irradiating the recording layer constructs with a laser beam of a wavelength 360 to 420 nm and a spot diameter 0.3 to 0.52 μm (1/e<SP>2</SP>) toward the substrate from the recording layer construct side. The recording is performed by regulating the writing power of the laser beam to a range of from 2 to 30 mW and the recording medium is formed by laminating the first recording layer construct, the second recording layer construct, to the n-th recording layer construct successively from the incident side of the laser beam. Grooves nearly equal to the grooves formed at the substrate are formed between the respective recording layer constructs and the each other's groove columns of the adjacent recording layer constructs are shifted by one or more columns with respect to the optical axis of the laser beam. The amounts of shifting are confined within the range where the writing pickup of a driver for driving the multilayered configuration type optical recording medium can follow.  <P>COPYRIGHT: (C)2004,JPO
