What is an “MMC Compliant” recorder?
Historically, each manufacturer of CD recorders used a different command set, and perhaps even altered the commands with each new recorder. This has placed a significant burden on CD-R software authors, who have to write new drivers for each new device. MMC (Multi Media Command) compliant recorders use a common command set. Programs that can write to one MMC-compliant recorder should be able to write to all others, and consumers should be able to use their choice of software without the long delays usually associated with the introduction of new hardware. The reality is not so kind, unfortunately, due to firmware bugs or deliberate deviations from the standard. Do not assume that a particular piece of software will work with your recorder simply because it works for other MMC-compliant devices. The spec sheets for recorders usually indicate whether or not the drive is MMC compliant. The MMC-2 standard is documented in ANSI/NCITS 333-2000. You can buy a copy of the standard from http://
