Narrative:

On taxi for departure, I requested procedural instructions from ground control due to unfamiliarity with airport. Ground control helpful in directing aircraft from ramp to end of runway. I was instructed to pull to right of taxiway for aircraft run-up check. Upon calling ground control to report ready for takeoff, ground control instructed 'taxi to the runway, you are #1. Contact tower on...' (distance from run-up point to runway was approximately 100 ft.) these instructions were misunderstood to mean to taxi onto the runway. Upon contacting the tower, the tower controller informed me I had entered the runway without permission and cleared me for takeoff. I apologized for the misunderstanding, explained I was unfamiliar with the local procedures and departed. To my knowledge, fortunately, there was no aircraft on final approach. I believe this occurrence could have been avoided by clrer instructions from ground control such as 'taxi to the hold line and contact tower on...'
