Filed: 1989-08-03
Abstract: PURPOSE:To prevent the non-reading of the data in the case of a flaw being generated over plural recording parts, by changing the arrangement order of partitioned data whenever plural times recordings are performed and selecting the partitioned data in a preset optimum kind at reproduction time. CONSTITUTION:When a data is recorded 10 blocks each alternately on each track 22 of a magnetic tape 17 by magnetic head elements A and B, the arrangement order of the partitioned data in each partitioned data row is changed in a different order at a 1st time recording part R1 and 2nd time recording part R2 and recording is executed.

Thus the data on the Voxel is stored in the 2nd three-dimentional memory 4 and then added toward a viewing line by an addition means 5 to be displayed in the form of a reprojected picture having the stereoscopic feeling via a display means 6. Thus a reprojected image can be displayed with improvement of the stereoscopic feeling with addition of the means 3.
