Abstract
The proposed device for data recording and reading contains a disk drive, read-write heads, and a positioner. The surfaces of the drive disk contain tracks for storing data. The read-write heads are arranged over the corresponding surfaces of the disk. Each head overlaps the track through its width. The positioner is common for two or more read-write heads and provides the displacement of the heads in radial direction about the disk center. Each read-write head has an independent actuator.
