How To Burn Files To Disc
Any good business backup advice will tell you to store a copy of important data offsite. Your company can’t have all its eggs in one basket, so to speak. If your only copies of your business data are housed in a single building, what happens if there’s a fire or flood? Offsite backup can take several forms. Online storage is an attractive option these days, despite the occasional news story about an outage or security breach. Even taking home a thumb drive every night is better than nothing, even if it’s kind of risky. For serious offsite protection, however, you might prefer a weekly trip to your bank’s safe deposit box to drop off a backup on some form of portable media. And to avoid the temptation to overwrite the backups of previous weeks-as you might if you use a portable hard drive as a backup device – consider using write-once, recordable DVDs, CDs, or BDs (Blu-ray Discs). Optical discs are inexpensive, after all. They’re also impervious to strong magnetic fields, which can corrupt the data on a portable hard drive. Likewise, they don’t break when you drop them-another hard drive vulnerability. It’s possible to scratch a CD/DVD/BD, of course, but if you’re careful to handle them by the edges, store them in cases or sleeves, and refrain from setting them down bare on anything but a drive tray, you shouldn’t have many problems. Before we talk about the basics of writing data to disc, let’s do a quick brush-up on CDs, DVDs, and BDs in general. Optical media can be confusing, so let’s lay out each topic one by one.
Optical Discs Exposed
A CD/DVD/BD-writing drive uses a laser to burn pits, or dark spots, in a disc’s recording dye layer. That’s why people refer to writing data on an optical disc as “burning.” Later, optical drives can use lasers on lower power settings to read the pitted and unpitted areas (lands) of the dye layer as the 1s and 0s of binary data storage. There’s a reflective layer above the dye layer. Usually made of aluminum, the reflective layer bounces the laser back to the drive’s read head when there’s no pit in the way. This is why the data side of an optical disc looks kind of like a mirror. CDs, DVDs, and BDs are all the same physical size, which makes manufacturing easier. In order to store more data than CDs, DVDs and BDs use lasers of different colors (wavelengths), which can create finer pits. CDs store 650MB or 700MB; DVDs can hold 4.7GB or 8.5GB (DL [dual-layer] discs with two recording dye layers); and BDs have capacities of 25GB or 50GB (DL). Mini versions of each have less storage space. Note that you can’t modify the data on a store-bought movie DVD/BD, audio CD/DVD, or software CD/DVDROM (read-only memory), as these types of discs don’t contain recording dye. Instead, their reflective aluminum layer is stamped with an indelible pattern of pits and lands.
