I'm using a similar disk, with 60 slots and it works fine up to 3000RPM (max of my spindle) thru the parport.
The only issue I had was that I made it from blue acyrilic, which seemed to be transparent to infra red. Spray of black paint fixed it. The other sensor you can see is the standard sherline sensor, which I'm using for the index pulse (the white tape on the disk!)

Sensor is exposed as seen in pic. Datasheet attached.

Would you mind sharing your .hal file for reference!

Find attached hal and ini files.  Sorry about the REALLY slow response to this message!
