CD-R media is rapidly becoming popular because of its reasonable price and superior compatibility, and used by a wide range of users. Currently, recording of large volumes of data such as video are increasing, expanding the popularity of DVD media (4.7GB). The need for intermediate range capacity between CD-R and DVD is steadily increasing as users demand an easy to use and affordable type of large volume media. "HD-BURN" technology meets these needs and realizes the recording of large volume data at a moderate price. A recorded disc by "HD-BURN" technology is compatible with a DVD player, and allows, the player to read the disc with some modification of firmware.
SANYO Electric Co., Ltd. will disclose the technology used to read the media recorded with "HD-BURN" technology by a DVD player and will propose to other DVD drive makers that they adopt this technology as an industry standard. The picture above shows Sanyo's CRD-BPDV2 DVD-RW drive. The HD-Burn technology has been designed on the assumption that it will be used with a CD-R disc and a CD optical pickup for playback optical system. Compared to CD-R, the miniaturisation of minimum pit size and the modification for error correction method have achieved a high density recording media. HD-Burn achieves a 134.3 % improvement in reduction of minimum size and 148.9 % improvement in error correction, with an overall improvement of 2 times in recording capacity. Drive specifications (CRD-BPDV2) 1. HD-BURN read speed x80, write speed x36
2. CD-R/RW x24/x12/x40
3. DVD+RW/+R x4/x4/x16
4. BURN-Proof, FlexSS-BP
