Looking for accurate history of CD-R. Specifically, did data CD or music CD come first?
Digital Audio CD is a Digitised Analogue Waveform (specifically 16b @ 44.1Khz) = Data … therefore, the Data CD came first, although the CD was designed for Audio purposes.
A brief read:
CD-Rs have always been used for either audio or data so there is no answer to which was first.
