The invention discloses a near-line magnetic disk array library with contact points. The near-line magnetic disk array library comprises an all-independent driver set, a plurality of mechanical arms,and a controller. The all-independent driver set consists of a plurality of magnetic disk array module groups arranged in M rows and N columns, wherein the M and the N are integers larger than or equal to 2; the front ends and the rear ends of the plurality of magnetic disk array module groups are arranged externally; contact points are arranged at the front ends of the plurality of magnetic diskarray module groups and are provided with complete signal channels for connection with data management servers. The multiple mechanical arms can move along a row direction or column direction in a plane parallel to the front ends of the magnetic disk array module groups. The controller is used for controlling the mechanical arms to move to designated positions to realize connection between the data management servers and the magnetic disk array module groups, thereby completing data transmission. The near-line magnetic disk array library has advantages of high reliability and maintainability;and compared with the typical magnetic disk array formation, the library has the lowered cost and the stability of the equipment is increased obviously.
