Re: Korgutils floppy coding

Update: After further reading into the KorgUtils documentation, quadruple density is indicated, as the ten sectors per track use 1024 bytes per sector, for 10240 bytes data per track. (MS-DOS high density is 3.5" 80 track, 18 sectors per track, 512 bytes per sector, for 9216 bytes data per track.)

Re: Korgutils floppy coding

Thanks for the confirm. 1,3-RLL requires double the sample rate of delay modulation due to the flux-reversal timing, but no more bandwidth on the disc media than delay modulation, thus its common use on some early Seagate ST2xx/4xx hard discs via Western Digital controllers. I'll have to experiment ...

Korgutils floppy coding

I found more information from SourceForgeâ„¢ concerning an application suite korgutils: The korgutils README states 10 sectors per track on T-series workstations. (Most MS-DOS 3.5" disquettes are written for 9 or 18 sectors per track, based on a 14.31818 MHz base clock as in the IBM 5170 and 85xx/95xx...
