Abstract

Provided is an optical disc apparatus and an optical disc recording method, in which it is decided whether or not an optical disc recording medium is one of DVD-RW and DVD+RW when data is recorded in the medium. If it is decided that the medium is one of DVD-RW and DVD+RW, maximum length information is read out from a storage portion. The maximum length information contains a previously set maximum data length of data recorded to the medium by an optical pick-up portion in one recording operation. Data to be recorded is split into split data having a data length of the maximum data length or smaller. Further, an electric power value of a base electric power for controlling the semiconductor laser element to emit a laser beam with a bottom power is reset every recording operation of the split data.
