It may have many, it really depends on it's internal architecture. For example, some may combine pairs of tracks together to improve performance so that they can offer a better overall throughput since it has many different channels in parallel.
Most recent drives have a lot of heads and few platters. For example the Seagate Barracuda 7200.10 SATA which has 2 discs and 16 heads.

According to this site:
http://www.webopedia.com/DidYouKnow/Hardware_Software/2002/InsideHardDrive.asp
"The read/write heads read and write data to the platters. There is typically one head per platter side, and each head is attached to a single actuator shaft so that all the heads move in unison. When one head is over a track, all the other heads are at the same location over their respective surfaces."
It says "typically" so it's not always the case.

I would assume 6 heads, but I can't say for sure.
