On taxiout from corp parking area at den I mistook an aircraft back-taxiing on a runway for the taxiway I was cleared to taxi on. As I continued my taxi toward the runway the ground controller told me to stop. I stopped using maximum braking effort short of the runway as an medium large transport was departing on takeoff roll. I was instructed to make a 180 degree turn and taxi via the correct taxiway to the active departure runway 8L. No further incidents occurred. If the controller had not told me to stop I would have conflicted with the medium large transport. At the time of the incident I had flown 5.6 hours that evening already. If I had consulted the ground chart I would not have assumed I was headed for the correct taxiway. Normally we depart on 35L--my taxi-out takes me onto that taxiway. Taking time to review the ground chart and listening more closely to the instructions given by the controller and paying more attention to what I was doing would have prevented this almost tragic mistake from happening.

Title: LTT ON TAXI BARELY HELD SHORT OF TKOF RWY AS MLG TOOK OFF.
Narrative: ON TAXIOUT FROM CORP PARKING AREA AT DEN I MISTOOK AN ACFT BACK-TAXIING ON A RWY FOR THE TXWY I WAS CLRED TO TAXI ON. AS I CONTINUED MY TAXI TOWARD THE RWY THE GND CTLR TOLD ME TO STOP. I STOPPED USING MAX BRAKING EFFORT SHORT OF THE RWY AS AN MLG WAS DEPARTING ON TKOF ROLL. I WAS INSTRUCTED TO MAKE A 180 DEG TURN AND TAXI VIA THE CORRECT TXWY TO THE ACTIVE DEP RWY 8L. NO FURTHER INCIDENTS OCCURRED. IF THE CTLR HAD NOT TOLD ME TO STOP I WOULD HAVE CONFLICTED WITH THE MLG. AT THE TIME OF THE INCIDENT I HAD FLOWN 5.6 HRS THAT EVENING ALREADY. IF I HAD CONSULTED THE GND CHART I WOULD NOT HAVE ASSUMED I WAS HEADED FOR THE CORRECT TXWY. NORMALLY WE DEPART ON 35L--MY TAXI-OUT TAKES ME ONTO THAT TXWY. TAKING TIME TO REVIEW THE GND CHART AND LISTENING MORE CLOSELY TO THE INSTRUCTIONS GIVEN BY THE CTLR AND PAYING MORE ATTN TO WHAT I WAS DOING WOULD HAVE PREVENTED THIS ALMOST TRAGIC MISTAKE FROM HAPPENING.
