aLPHA Posted October 27, 2010 Share Posted October 27, 2010 Can we please close this topic? This is going nowhere. We have gone over the same facts over like...3 times. Link to comment Share on other sites More sharing options...
Lair Posted October 27, 2010 Share Posted October 27, 2010 I'm pretty sure of two things:1) "Data" on a disk is actually a series of tiny indentations on the underside that is read. The laser is fired at the disk and if it doesn't hit an indent then the laser hits a sensor, if it does then the light scatters and the sensor picks nothing up. These two options produce your ones and zeros. Therefore, data on such disks is in fact physical. 1) I believe you have this backwards. I believe he does NOT have this backwards. Or is this the same reverse fail from the Lego Universe image topic? Can we please close this topic? This is going nowhere. We have gone over the same facts over like...3 times. How about we NOT close this topic and you stop asking for topics that are not yours to be locked? Seriously, it's just annoying. It was when sonic did it long back and it is now that you're doing it.

Let me explain what he said to make it easier: The laser hits an indent and it picks nothing up, creating a 0. The laser does not hit an indent and it picks up a 1. Wait, now I am a little confused. Can we have someone who isn't me or Lair explain whether the indents are are 0 or 1? Link to comment Share on other sites More sharing options...
Cirevam Posted October 27, 2010 Share Posted October 27, 2010 The laser hits an indent and it picks nothing up, creating a 0. The laser does not hit an indent and it picks up a 1. I'm pretty sure this is the way most disk readers work, though the software that reads the data in could reverse them if it wanted. It could interpret a pit as a 1 and a flat spot as a 0. Bits are bits, it's just how you interpret them. Link to comment Share on other sites More sharing options...

I actually didn't specifically say which option produced which effect, as I'm not too sure myself. Were I to specify, I would have used a word like "respectively" in my post. *searches Google* A land represents a 1 and a pit represents a 0.
