Specially developed for professional studio and location recording, and broadcast use, HHB MiniDiscs exceed Rainbow Book specifications and exhibit block error rates ten times lower than consumer MD media.

With an extended recording time of 80 minutes 59 seconds, the MD80 uses an advanced thin film sputtering technology to apply recording, dielectric and reflective layers to a polycarbonate substrate, which is protected by a tough UV coating. The precision manufactured stamper ensures consistently accurate tracking for every disc and a special lubricating agent results in the best possible recording head contact. A durable shell combines with a foil shutter assembly to protect the disc from contamination.
