Abstract
Abstract A disc recording apparatus includes a first encoder, a memory, a second encoder, a head apparatus and a controller. The first encoder compresses an input signal. The memory once stores the compressed data compressed by the first encoder. The second encoder encodes the read out data from the memory in a predetermined unit. The head apparatus is supplied with the recording data from the second encoder and records the recording data on the disc. The controller controls the memory and the head apparatus so that when data is left in the memory in the record stop state, the record operation by the head apparatus is intermitted after the data in the memory is read out and entirely recorded on the disc.
