Recording apparatus, recording method and recording medium

摘要

A recording apparatus includes a recording unit that performs a recording operation to each layer by performing laser light illumination to a recording medium which has (n+1) or more layers as a recording layer and in which a test writing area of each layer is formed between at least n consecutive layers and at a position in which the test writing areas are not overlapped with each other when seen from a laser light incident surface side, and a controller that sets the n consecutive layers to be a recording target layer in the recording operation including a test writing for laser power adjustment and causes the recording unit to execute the recording operation to the n recording target layers, wherein n≧2.

主权项

1. A recording apparatus comprising:
one or more processors operable to: set a first group of n consecutive recording layers of a recording medium as recording target layers, wherein each of the n consecutive recording layers comprises a test writing area, wherein the recording medium comprises m+1 recording layers, wherein the recording medium comprises (m−n)+2 groups, wherein m≧n and n≧2, and wherein for the first group, a position of the test writing area of each of the n consecutive recording layers is non-overlapping with other of the n consecutive recording layers in a laser light axis direction; and perform a recording operation to record user data simultaneously on each of the n consecutive recording layers of the first group based on test writing on the test writing area of each of the n consecutive layers, wherein, in an event the recording proceeds to a new recording layer next to the n consecutive recording layers of the first group, as seen from a laser light incident surface side, the one or more processors are operable to close the recording of the recording layer positioned at a depth side as seen from the laser light incident surface side, of the n consecutive recording layers of the first group, and set a second group of n consecutive recording layers, comprising the recording layers of the first group other than the recording layer for which the recording is closed and the new recording layer, as new recording target layers.
