Recording device

Abstract

A recording medium which is replaceable with a conventional CD player and from which a host reproducing device can reproduce high-quality sounds. The recording medium is provided with a first recording area (3) in which digital audio signals which are sampled at a prescribed sampling frequency and quantized with a prescribed number of bits are recorded, a first management area (2) in which the information required to manage the digital audio signals recorded in the area (3) is recorded, a second recording area (6) in which the digital audio signals corresponding to the digital audio signals recorded in the first recording area (3) are recorded, and a second management area (5) in which the information required to manage the digital audio signals recorded in the area (6) is recorded. Identification data representing the presence of the plurality of recording areas are recorded in the first management area (2).

Problems solved by technology

However, due to loss of compatibility with CD-DA formatted CDs, such CD-R discs cannot be played back by ordinary CD players

[0019] Further, there is a limitation on the traditional format of CD-R discs

That is, for example, if in this way, two areas respectively called Audio Sessions recorded in CD-DA format and Data Sessions recorded in CD-ROM Session formats are mixed together, and the produced CD-R disc is played back with an ordinary CD player. Since codes that may not be recognized are recorded, there is a possibility that the audio track recorded in the audio session playback of the audio data becomes impossible, and / or the data of the data track recorded in the data session segment may be erroneously played back as audio data
