Abstract

The present invention relates to a magnetic disk control apparatus capable of utilizing a data region of a track. The data read/write controlling apparatus according to the present invention comprises a unit for serially reading a signal series constructed of a servo signal and data which has been recorded on a recording track; a unit for generating a first read/ write control signal in response to the servo signal of the read signal series; a unit for generating a second read/write control signal between the generation of the servo signal and a generation of a servo signal subsequent to the first-mentioned signal; a unit for writing given data into the data region of the recording track in response to the generation of the read/write control signal; and a unit for externally outputting data read out just after the read/write control signal is generated.
