Narrative:
On the takeoff roll we experienced the notorious 'dirty sock' smell. The smell was quite strong. I elected to continue the takeoff as we were already above 80 knots. As we began our climbout the smell began to fade; and eventually seemed to go away outside an occasional whiff detected by myself or my first officer. We were unable to put our oxygen masks on during the event as we were task saturated flying the airplane. I sent an ACARS to dispatch to notify them of the smell and that we would need maintenance in ZZZ1. Dispatch asked if the smell had been present in the cabin; and after speaking with my flight attendants I confirmed that they had not noticed anything. Upon arriving in ZZZ1 I wrote up the discrepancy as 'dirty sock smell in cockpit only'. ZZZ1 maintenance deferred pack 1 and the smell was not noticed on subsequent flights.as additional information based upon my review of the aircraft logbook; this has been a recurring issue with this aircraft; having been written up no less than 3 times in the last month. The pack that was deferred is also associated with an engine that has had multiple write ups for high lp (low pressure) vibration and seems to have a high rate of oil consumption.
