We currently use a 7261 NEC chip as a ST506 controller.
Problem is that it can handle only up to eight heads per
spindle.  We would like to go to higher capacity drives
than the 50 MByte Hitachi/Atasi we now use.  The possibilities
are: 1) go to higher density drives, like maxtores or acropolis,
or 2) somehow increase the number of heads that we can use.

Questions are: 
1) does anybody know about the higher density drives mentioned
above?  any feedback would be appreciated since we don't want
to be "first kids on the block" with these drives.

2) has anybody hacked a 7261 to handle more than eight heads
per spindle?  we've thought of using the REDUCE WRITE signal to
split the heads into two "banks", but that seems ugly and
would disallow REDUCE WRITE.
