The first digital tape recorder was demonstrated in Japan in 1967, with the first digitally mastered records appearing on the Denon label in 1972. The first commercially available digital audio recorder was the Sony PCM-1. Introduced in 1977, the PCM-1 converted an incoming analogue signal into a digital one, which was then recorded onto a standard video cassette in a VCR. Initially, digitally mastered records were still released on vinyl disks in the analogue format. In 1982, however, Sony and Philips released the first compact discs and players. On a CD, the digital information was embodied as millions of microscopic bits in the reflective aluminum coating of the disk.
