Whole track writing code?

[Linards Ticmanis <ticmanis@gmx.de>]

Hello,

I wonder if anybody here has a piece of whole-track writing code? I mean 
a piece of code that runs on the Apple and that can write a whole 
Disk-II track at once, and preferably one that works on pre-nibblized 
data, just writing it to the disk with the correct timing. I'd assume 
that nibble copiers contain such code, but before I put in all the work 
to extract such stuff, I'd be glad if somebody already had the necessary 
code available.

What's more, is a list of useful JSRs or CALLs into DOS 3.3 online 
somewhere? Like, for example, a JSR to move the head to a certain track.
