摘要： An apparatus for recording binary information on a flexible magnetic disk of small dimension, comprises a rotatable hub connected to a plate on a first surface of which is formed a spiral guide. The hub has a cylindrical portion engageable accurately with a corresponding central hole of the disk and it is provided with a radial driving dog engageable on the fly, and with play, with a corresponding radial notch opening out of the central hole. A recording head is mounted at the end of an arm which has an element cooperating with the spiral guide of the plate for being moved, radially with respect to the disk, in synchronism with the rotation of the plate and of the same disk.
