aug 6, 1974 - Standalone hard disc recording
A hard disk recorder (HDR) is a system that uses a high-capacity hard disk to record digital audio or digital video. Hard disk recording systems represent an alternative to reel-to-reel audio tape recording and video tape recorders, and provide editing capabilities unavailable to tape recorders. The systems, which can be standalone or computer-based, typically include provisions for digital mixing and processing of the audio signal.
