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.

HHB's MDD140 has been specifically designed for use in multitrack recorders incorporating the MD Data format (including models from Sony, Yamaha and Tascam).

The MDD140 excels in the critical areas of low block error rates and high carrier to noise ratio. Magnetic field modulation direct over write is used to record new data which markedly increases write speeds and achieves 100,000 read/write cycles. Please note that the MDD140 will not work in conventional MiniDisc recorders.
