Hello, all. The above referenced ca. 1980s MIDI sequencers (termed
"Disk Composers" by Brother) all appear to use the same internal 3.5"
FDD. The spindle is belt rather than direct driven. I can't find any
specific belt info for these devices on line except for the FB-100
Brother drive which was intended for use with their line of knitting
machines. I have the MDI-30 and I think a 8.5" or 9" circumference flat
belt might work but if anyone can provide some additional detail it
would be most welcome. Thanks for your time and comment. Sincerely,

I just replaced the belt on a PDC-100. I got it from
https://www.turntableneedles.com. A 9.8" small square belt worked just fine -
their part # SBS9.8. Cost $5.

I expect he's long gone. If not a stationery belt should do the job.

Hello, and I was the OP on this. I subsequently solved my dilemma with
a replacement flat belt from Suburban Electronics. They have quite a
selection of these small drive belts and at very reasonable prices.
Shipping cost is somewhat less reasonable. Sincerely,

why not replace the disk drive with one of these? ::

It eliminates the diskette altogether and instead you use a USB flash drive
€œmemory stick€� to move songs to your computer.

These USB floppy drive replacements are drop-in, plug-in replacements with
apparently no fuss.

I have a "real" floppy drive that plugs into a USB port.
I needed it to install Windows Server 2003 on a Sunfire server.
