Shanna,
Lite-On is a CD-RW manufacturer that sells to OTHER manufacturers, who simply re-badge the item and sell it under their own name. You can usually tell a Lite-On from several clues. The outside box may say "Smart-Burn" (for error/buffer underrun protection), which is the trademark name for Lite-On's technology. In the case of Sony, if it is a Lite-On, they may have been given permission to re-badge the technology too, which they call Power-Burn. In some cases, the re-badging companies use MULTIPLE vendors (I presume based on pricing and availability), these units usually don't refer to a specific trademark name for buffer underrun or error protection technology (they'll just refer to it generically as I just did). For example, in the case of CenDyne (commonly sold at OfficeMax), you need to check the UPC/serial # on the box, if it begins w/ LTR..., it's a Lite-On. If it begins w/ CW... something, it's probably an Acer.
Why does it matter? The Lite-On's (in my opinion) are the poor man's Plextor, I LOVE 'EM, they work very well, and fully support CloneCD (for making backups of your copy protected CD's!). In many cases, an Acer, Ricoh, even big names like Pioneer, Toshiba, often can NOT. Lite-On's use to be of less than stellar quality, but have improved tremendously in the past couple years. And they provide frequent firmware updates, necessary for accurately detecting and burning new media as it becomes available.
Lite-On does sell its own drives directly (check out Newegg.com, they're selling their 48x24x48 for $61, and 52x48x52 for $66, good deals considering what a Plextor, the KING of CD-RW, costs, about TWICE as much for essentially the same capabilities). Btw, the ONLY difference between the 48x and 52x in this case is the fireware, so you could just buy the 48x from Newegg.com and apply the firmware update, save $5 bucks.
But why even pay $61 or $66, when you can pick of the re-badged units for $20 - $30 after rebate! That's why everyone is looking for the Lite-On's. When you compare the capabilities/features of a Lite-On to a Plextor, the Lite-On is an incredible value.
Btw, here's the Lite-On site if you're interested, it's a Taiwan site, so a little awkward to navigate, but dig down a little and you'll find the firmware updates:
