ク制御装憂 置。[Claims for Utility Model Registration] A magnetic head that uses a removable flexible disk as a recording medium to read/write data in contact with the recording medium, and a head load controller that brings the magnetic head into contact with or separates from the recording medium. A flexible disk device having a structure and a seek mechanism for moving the magnetic head between concentric recording cylinders on the recording medium is used to record half or more of the data recording capacity of one track. A gland having a data buffer of a large capacity and performing data transfer across the recording cylinders, first performs data transfer between the buffers for the latter half of the track from a sector at an intermediate position of the track after seeking, A flexible disk control device, characterized in that it is provided with means for successively processing the first half of the track.
