To obtain a disk device capable of recording or reproducing in a proper timing when a disk-like recording medium consisting of a multi-spiral track is recorded or reproduced, whatever arrangement is made for a recording means or a reproducing means.

The information on the arrangement angle of the recording means of the disk recorder is recorded on a disk-like recording medium at the time of recording operation. This information is distributed to each track to be the information on the arrangement angle of the recorded data. By this information of the arrangement angle and the arrangement angle information of the reproducing means, the selection is made which track is to be reproduced by which reproducing means at the time of reproduction is executed, then the delay amounts of delay means 15, 16, 17, 18 are set. As the result, the data of which timings are mutually coincident, are integrated in a data integration part 20.
