I believe in solving problems, not sharing them.

Quote:Originally posted by JO753: We were mostly tokking about tape vs dijital, including dvdr. I only mentioned The Omega Man az an example uv commercially recorded DVDz going bad. I've had several over the yirz. Funny story: I put a DVD movie from the library in and it woudnt play. I take it out and it feelz too thick. Then a clear layer slidez off the bizness side! I'm thinking its this disk, but then it playz fine and I woc the movie. (dont recall wut it wuz) After, I check the previous movie, also from the library, and thats wer it came from! In other wordz, I'd woct it with no problem but wen I took it out uv the player it left the bottom clear layer behind and I didnt notis.
Quote:Originally posted by JO753: Also, I'v lost way more stuff on dijital formats than I ever did on tape. CDr and DVDr disks are very unreliable. Hard drivez die. Virusez get in and corrupt data.
Quote: Windowz goofs up ALL THE TIME. Even commercially prodused DVDz go bad. I started watching Omega Man last week and it stalled at chapter 14, locking up the chintzy LG 4K player so I had to pull the plug. Tried it in a Sony Blu Ray player and an ancient Toshiba DVD player and they stalled in the same spot, but at least I coud just hit the stop buttun and take the disk out. I have cassete tapes from the 1960z that still play! I hav VHS tapes from the 80z that still play. HEY! Maybe I coud rig up a VCR az a backup for my hard drive! It woud only take about 200 tapes! or iz it 20,000? I forget.

Quote:Originally posted by SIGNYM: I think, if you really want to be fussbudgety about the whole DVD/CD v VCR issue, you could prolly consider tape to be "digital", too.
Quote: All it is is mylar (stretched polyester) coated with a resin in which magnetizable particles are embedded. The only thing that's recorded is whether the particles are magnetized in one direction (0) or another (1).
Quote: Hard drives are the same, aren't they?
Quote:Just records of which way the magnetizable particles are lined up (0, 1).
Quote: In both cases, a magnetized segment of tape or disk spinning past a "read" head will generate a small current.
Quote: How those are then decoded depends a lot on software.
Quote: In the old tape format, it was possible to record anything without copyright. But some evil genius figured out a way to copyright protect commercially recorded VHS tapes by imposing an additional signal on to the info which had to be electronically stripped out for viewing. The problem with VHS tapes is that the magnetized portions slowly lose their magnetization over time, even if stored under perfect conditions and not physically degraded by moisture, heat, being stepped on etc.
Quote: DVDs and CDs are a different story. A laser is typically used to change the OPTICAL property (reflectance or color) of a spot on a metalized hard plastic disc.
Quote: These could also be considered "digital" since there are only two states (0, 1) to the media.
Quote: However, once written some discs can't be erased and rewritten. The metalized plastic is protected by a clear plastic layer, but if there are small defects or cracks in the overlay oxygen gets underneath and oxidizes (dulls) the metal, ruining the stored info.

Goodbye, kind world (George Monbiot) - In common with all those generations which have contemplated catastrophe, we appear to be incapable of understanding what confronts us.
