Your right, not too good on multiple errors.
You might be looking at a drive issue. Have you tried taking
the disk out and putting them back in after shifting them
in the envelope? ( I'm assuming they're floppies )
These are genuine read errors, not problems with the drive. Given
the age and condition of the disks, I'm not surprised. 100 tpi
floppies were never that reliable to begin with.
No--my question relates to MFM error recovery techniques. Since my
"data separator" is in software, I'm assuming I can do some clever
things that I couildn't do with a "dumb" PLL data separator.
