ABSTRACT:
A library apparatus includes a cell unit having a plurality of cells arrayed in a matrix, a holder to insert the storage medium to one of the cells or extract the storage medium from the cell, and a position controller to move the holder over the cell unit in X-axis and Y-axis directions to position the holder at a desired position. The holder has a reading unit configured to acquire data of the edges on both sides of each cell. The position controller determines each position of the cells on the basis of the data of the edges acquired at a plurality of positions while moving the holder in a predetermined direction from a predetermined position of the cell unit.
