METHOD OF RECORDING DATA IN MULTILAYERED RECORDABLE OPTICAL RECORDING MEDIUM, RECORDING AND REPRODUCING APPARATUS FOR RECORDING THE DATA IN THE RECORDING MEDIUM AND THE RECORDING MEDIUM
First Claim
1. A method of recording data in a multilayered recordable optical recording medium having N (N is an integer of 2 or more) recording layers each of which layers includes a test recording area where test recording is executed for obtaining an optimum recording condition for actual recording, and which method includes a data recording step in which data are sequentially recorded in the recording layers from a first recording layer at the farthest position to an Nth recording layer at the nearest position viewed from a recording and reproducing laser beam inputting direction in order, comprising:
- a test recording executing step which sequentially executes test recording in recordable recording layers having unrecorded parts from a pth recording layer (1≦
p≦
N) at a farthest position in the recordable recording layers to an arbitrary qth recording layer (p≦
q≦
N) in the recordable recording layers at the farthest position to the nearest position viewed from the recording and reproducing laser beam inputting direction;
a test recording range using step which sequentially uses a plurality of test recording ranges formed by dividing the test recording area in a radius direction from one end to the other end of the recording medium in each of the recording layers (hereinafter this direction is referred to as a test recording direction); and
a shifting step which shifts the test recording range of an (m+1)th recording layer by a predetermined shifting distance relative to the test recording range of an mth recording layer in a direction inverse to the test recording direction.

Abstract
A method of recording data in a multilayered recordable optical recording medium is disclosed. When test recording is executed in a multilayered recordable optical recording medium having N recording layers (N is an integer of 2 or more), a test recording range in a test recording area of an (m+1)th recording layer is shifted relative to a test recording range in a test recording area of an mth recording layer by an amount greater than a difference of decentration amounts between the mth and the (m+1)th recording layers or a maximum decentration amount in the N recording layers. The shifting direction is inverse to a test recording range adding direction in a radius direction of the recording medium.
