true JPMick but there must be numbers out there for what the Storage of say, a 2 hour VHS tape recorded at the 2 hr Speed. That's got to be some sort of equivalent; it's analog, but like MP3, there's some kind of compression going on, so its got to be, and here's a total guess, perhaps 5-10 MB/sec. Actually not a total guess, as a DVD Recorder I had showed the bitrate when youd dub from a tape, and I think that was about it for a 2hr rec speed; about 10 MB/sec. Wow could that be off.
It is worth noting that some music producers, notably Machine still swear by running 2 inch analog tape over Any form of digital recording.
[edit-o-rama; why do i annouce this?]
Yes I was explaining why DVD is better, but then my brain started, and thats a bad thing.
It's like this. Kodak Film is analog. Recording tape is analog. Its basically a film, emulsion for Kodak; magnetic particles in some Metal Oxide for tape; and with both of those, you have a Huuuugggge amount of capacity, in terms of the amount of info it could carry. A few years ago it would be tough to argue that digital photography could even approach the 'fineness' of a film emulsion. Now there are some pictures you have to Really Zoom in on before you can see whether its pixels or film.
So the analog has this advantage of being able to record in a way that is quite different. Digital recording assumes we hear 20Hz-20,000Hz, then doubles it to 44.1 or 48 kHz in todays run of the mill 16/24 bit recorder. Now uncompressed i think a .wav file is 1.4MB a second, thats a Shitload of Memory compard to an Mp3.
Any digital cuts off the 'air' above 20,000KHz and below 20Hz, and many artists argue it makes a big difference in the recorded sound. You can hear it in Any MP3. The MPEG algorith, first thing, is chucks out anything outside of 20-20K, so its a 'Lossy' algoritm. At 64kB/sec its unlistenable, 128 is ok except for transients, 192 is minimum for a real sound system and why am i rambling about this...
It's all obsolete now; with 1 gig Compact Flash and Smart Media cards; your entire collection of music and movies will be stored in some quantum computer that will store 1 Terrabyte as an afterthought, and be so small our stupid big hands will be the limiting factor, as they are now. Image a HAL-9000 the size of a GBA. The only problem is the format war; whats it gonna be? we have a bazillion ways to get data in/out; modem, USB, firewire, and about 8 different formats of Memory Card. This is a bit more complex then VHS vs. Beta, and remember that one? The inferior format won out.
