problem with TClonesArray

hello,

I've made my own class Track consisting of a header-file Track.h and its 
implementation code track.cpp.

this is track.h :
------------------------------

#ifndef TRACK
#define TRACK


class Track: public TObject {

private :

         UInt_t PulseHeight;
         UInt_t ChannelNumber;
         UInt_t DataValid;
         UInt_t OverPedestal;

public :
	
	    Track(ULong_t value);
		~Track() {;}
        UInt_t GetPulseheight()   {return PulseHeight;}
        UInt_t GetChannelnumber() {return ChannelNumber;}
        UInt_t GetDatavalid()     {return DataValid;}
        UInt_t GetOverpedestal()  {return OverPedestal;}
};

#endif
-----------------------------


and this is my track.cpp :
-------------------------------
#include "track.h"


void Track::Track(ULong_t value)
{
 PulseHeight=(value >> 0 & ~(~0 << 12));
 ChannelNumber=(value >> 0 & ~(~0 << 23));
 DataValid=(value >> 0 & ~(~0 << 31));
 OverPedestal=(value >> 0 & ~(~0 << 32));
}
-------------------------------------------

Then I try to make a TClonesarray in the root interpreter, but the
TClonesArray  returns an error saying he doesn't find the class :

both the track.h and the track.cpp are in the same directory

I'm running root for under windows NT 4.

What am i doing wrong here ?
