If mass of disc(cylinder like reel) is considered only. then
Torque equation, calculate torque due to tension about the centre, T X R = I x angular acceleration
Force equation, mg – T = M a
Calculate, and find the acceleration..

IF>> mass of the string is given and as it is decreasing, then concept would be something different....

Good Luck
