Digital optical tape archival storage systems and methods are disclosed. A digital optical tape recorder simultaneously writes data and two or more guide tracks onto an unformatted digital optical tape recording medium. A digital optical tape reader includes a camera and an image processor. The camera captures a two-dimensional image of the digital optical tape recording medium including the data and the two or more guide tracks. The image processor extracts the data from the two-dimensional image based, at least in part, on the guide tracks.

A head driving device includes a base member, a head supporting member, a beam member, a piezoelectric unit, and a reinforcement member. The reinforcement member includes a first portion and a second portion. The first portion is arranged between a first end portion in a length direction of a head member and the base member. The second member is arranged between a second end portion in a length direction of the head member and the base member. The reinforcement member allows the head supporting member to move in a direction along a surface of tape and controls the head supporting member from moving in a thickness direction of the head member.
