What is "Dual Layer technology"

[Tornadic]

I am thinking about getting a DVD ROM. Could you tell me what "Dual Layer technology" is and whether I need special discs for it?

It's a fairly new home recording standard for DVD discs (it's been around on movie DVDs for ages though). As you can see from the description, it allows for the storage of around 8Gb worth of data (compared to the 4.7Gb of single layer discs), and yes, you need a supported drive with special dual layer discs (which cost a fair bit).

I recommend the latest drives from either Pioneer (DVR-109) or NEC (ND-3520A).

It is just where you can record data on both sides of the Disc, and yes it is a special disk, and I want to say I say them at best buy for 15 bucks for 3 of them, but I am nto sure about that one.

Those are dual-sided discs jfountain, not dual-layer discs. ;)

Far better value for now though. :-|
