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 non-linear editing capabilities unavailable using tape recorders.

Standalone recorders use standard A/V connections, including RCA connectors, TOSlink, and S/PDIF for audio and RF, composite video, component video, S-Video, SCART, and FireWire for video. High-bandwidth digital connections such as HDMI are unlikely to feature as recorder devices are not permitted to decrypt the encrypted video content.
Optical disc authoring, including CD, DVD, and Blu-ray Disc authoring, is the process of assembling source material—video, audio or other data—into the proper logical volume format to then be recorded ("burned") onto an optical disc (typically a compact disc or DVD).
Disc quality: optical disc recorders detect the available speed options based on the data which is available on the disc itself. However, some low-quality discs make a high-speed option available to the software, while the burning process can never reach that speed in practice. The reading and writing process may not happen at a steady speed.
One use of this technique, for example, is to burn track introductions to be played before each track starts. A CD player will generally display a negative time offset counting up to the next track when such pre-gap introductions play. Pre-gap audio before the first track of the CD makes it possible to burn an unnumbered, "hidden" audio track ...
A DVD recorder is an optical disc recorder that uses optical disc recording technologies to digitally record analog or digital signals onto blank writable DVD media. Such devices are available as either installable drives for computers or as standalone components for use in television studios or home theater systems .
Reliable writing of discs. Verification done in hardware by the drive, so post-write verification by software is unnecessary. Software verification is disabled in all current DVD Video Recorders. Disc defect management designed to safeguard data. DVD-burning software may not be required — discs can be used and accessed like a removable hard disk.
