Narrative:

Pilot and aircraft were on the ground under control of airport tower. Pilot had made a full stop landing on a parallel runway, reported clear of the active and requested taxi to parking area. Tower said 'taxi taxiway A11, remain on the frequency.' pilot repeated clearance to tower. Tower did not respond. Pilot passed stop line before an active runway continuing taxi. Tower called to instruct pilot that he should not enter active runway. Pilot returned to stop line. Pilot was cleared to pass the active runway and contact ground. Pilot requested taxi to parking. Pilot was cleared to parking and given a phone number to call. Pilot spoke to supervisor at phone number who said that they were required to file a report with the office about possible runway incursion and there appeared to have been a 'misunderstanding' between pilot and controller. Pilot asked if supervisor had listened to tape -- answer 'yes.' pilot asked if clearance had included a hold short of active runway instruction -- answer 'yes.' pilot asked if he had read back clearance omitting a hold short instruction -- answer 'yes.' pilot asked if controller had called to correct incorrect readback -- answer 'no.' pilot asked if that was why supervisor was using word 'misunderstanding' -- answer 'yes.' traffic on ground and in air unusually bust at time. Military aircraft both in air and on ground was active at time. Commercial traffic on ground waiting to depart the active runway -- it was not moving.
