PROBLEM TO BE SOLVED: To perform nonlinear editing without deteriorating a transfer rate of a reproducing data even when a slow accessible storage device is used for housing material data and also the number of editing points is increased. SOLUTION: At the time of deciding an editing point, a data adjacent to the editing point in the material data is copied from a material disk device 21 to a work disk device 22, and when the data adjacent to the editing point is to be reproduced, at the time of reproducing the edited data, first, the copied data in the work disk device 22 is read out to be the reproducing data, and also in the meantime, a data to be reproduced in the material disk device 21 is accessed, and after completion of this access, the read data from the theme disk device 21 becomes the reproducing data. |
