Abstract
The magnetic recording apparatus according to the present invention comprises a recording medium in which servo information items are provided on tracks at a predetermined interval, a head for scanning the tracks of the recording medium, a read/write circuit for reading/writing data with respect to each of recording units on the recording medium through the head, a servo circuit for sequentially reading the servo information items through the head, a first control section for performing control on the basis of the servo information items read out by the servo circuit such that drive power is supplied to the read/write circuit, a predetermined time period before a time point when the read/write circuit starts reading/writing of data with respect to a target recording unit, and a second control section for preventing supply of the drive power to the read/write circuit, upon completion of the reading/writing of the data by the read/write circuit.
