Hard Disk stepper

[Konstantin]

Hi.
I want to do some testing with salvaged stepper from a harddisk (samsung) wich has 4 wires. But I thought that 4 wire are bipolar steppers and those have 2 coils wich do not cross leads.
This stepper has the wires labeled as A, B, C and CT and Ive tested them with a digital ohm meter and get :
A-B : 4 Ohm
A-C : 4 Ohm
A-CT : 2 Ohm
B-C : 4 Ohm
B-CT : 2 Ohm
C-CT : 2 Ohm

Is this right for a bipolar stepper?

Any coments on this motor?

Will this be a variable reluctance four windings motor?

[Konstantin]

Actualy it looks like a normal variable reluctance motor.

Anyone uses those in projects?

The chip wich drives the stepper located on the HD is L6269.
I wonder if it is possible to use the driver and hook it up to the LPT somehow.
I am going to read the info on this L6269 on ST's http://www.st.com/stonline/books/ascii/docs/6626.htm
