I always wondered if putting the data side of two DVDs together is bad? I know their optical and not magnetic, but im still not sure if doing that is a bad thing? GriFF
Facing the bottoms (data side) of DVDs together should not be problem because the two polycarbonate halves will face each other. There may actually be less scratching when they slide together compared to a plastic base sliding against a coated upper half. Since the data are mechanically recorded, there is no problem with interference compared to magnetic recordings where fields interact and cause print-through from layer to layer. (The magnetic prints are eliminated when the tapes are rewound and new prints begin to form--a major reason for exercising tapes once a year. This is an analogue phenomenon for magnetic tape. Data tapes that suffer from "bit shift" due to the same effect would have such unstable particles that they would be unsuitable for recording in the first place.)
Pretty much common sense stuff here... I mean come on: Do Not Write or mark in the data area of the disc? Ooohhh I thought the Shiny side is where I'm supposed to write, NOT THE CLEAR WHITE SIDE!! Silly me..
You'd be surprised, lol. My father just bought a new hand held camcorder that records directly to DVD. After he was done filming he asked me if it was alright to write on the silver surface with a marker. He is, by no means, an idiot but just misinformed as to how DVDs work. The last camcorder he had recorded directly to VHS tapes, and he rarely watches DVDs.
