The invention discloses a near-line disk array library with a read-write head, and the near-line disk array library comprises a full independent driver set which comprises a plurality of disk array module groups which are arranged in an M*N matrix, wherein M and N are integers which are greater than or equal to two. The front and rear ends of the plurality of disk array module groups are set outwards, and the front ends of the plurality of disk array module groups are provided with a first read-write head. The near-line disk array library also comprises a first mechanical arm which can make movement in a plane parallel to the front ends of the disk array module groups; and a controller which is used for controlling the first mechanical arm to move to a specified position, so as to connecta data management server and the disk array module groups through the first mechanical arm and to achieve the data transmission. The full independent driver set provided by the invention is reasonablein structure, and the mechanical arm is used for the management of all disk array module groups in the full independent driver set, so the management efficiency is high, and the reliability is good.
