ChanServ changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic.

The unformatted capacity of a single density disk is 250KB
<cr1901_modern>
(err, per side)
<cr1901_modern>
It has a theoretical storage capacity of 5876 bits per inch
<cr1901_modern>
So, to get the number of bits per track, I do: (250KB * 8 bits)/40
<cr1901_modern>
50000 bits per track
<cr1901_modern>
with a theoretical storage capacity of 5876 bits per inch, that means the circumference required at MINIMUM to store 50000 bits is... 50000/5876... 8.5 inches
<cr1901_modern>
That is a circle of radius... 8.5/(2*pi) 1.35 inches... does that sound right?
<cr1901_modern>
I don't have a ruler handy; can anyone measure out 1.35 inches and tell me if it's remotely close to track 40 on a 5.25" floppy?
<cr1901_modern>
It sounds reasonable, but 8.5 inches is a lot...
