DVD burners optimize their ability to write to different brands of DVDs by internal "write strategies" that control the laser power and pulse settings to maximize its accuracy with each different dye formula, reflector density and plastic doping chemistry for each brand of blank DVD disc.

When a disc is inserted, the drive reads the factory media ID off the disc and queries its internal list of known disc brands and write strategies. If the disc is listed, then it uses the write strategy for that disc.

If a write strategy for a particular disc brand is not present in the drive's firmware, it tries to estimate how best to write to the disc by writing to the small re-writable "power calibration" area on each unknown disc type to see which power setting might produce best results for the unknown disc brand.

In some cases, the firmware is unable to produce reliable burning with a particular disc brand, and rejects the disc as having a "power calibration error" or "illegal disc" or a similar error. This error is generally not related to disc quality issues, but is simply a result of the drive not having the latest firmware in it that lists the particular disc brand.

From time to time, drive makers test additional brands of DVD discs and then update their firmware with new write strategies for those newly tested discs, enabling their drives to work with more brands of DVD discs.

All DVD writer owners need to frequently check with their drive manufacturer to see if there is a new firmware upgrade available for their drive. That way they can expect to enjoy working with more brands of discs, and more reliably with the discs that they already can use.

Newer firmware for your drive means it can burn more brands of DVD-R, DVD+R or CD-R discs, more accurately, and usually faster. Once burned with this newer firmware, they will also play back with fewer errors on DVD players. DVD burners use special "write strategies" in their internal drive firmware to customize the way their laser works with each different brand of blank DVD. Each brand of DVD-R or DVD+R uses a different color of bottom dye, plastic composition and silver reflector density. This means the burner's laser must be adjusted for each different disc. From time to time, your drive's manufacturer tests more discs and develops new firmware versions to include those new disc brands and types into their drive's internal list of compatible blank DVDs, which is kept on a special "firmware chip".
