The development of high density recording technology "HD-BURN" : "HD-BURN" enables us to record the double density data on a ordinary CD-R

Abstract

We have developed the high density recording technology "HD-BURN" which enables us to record the two times volume data (1.4GB) on an ordinary CD-R media (700MB). This technology has been designed on the basis of using a CD-R disc and a CD optical pickup for playback optical system. Compared to CD-R, the miniaturization of minimum mark size, modulation and the modification for error correction method have been done to realize a high-density recording. A recorded disc by "HD-BURN" technology has an affinity of a DVD player, and basically, the player will be able to read the disc with some modification of firmware.
