PROBLEM TO BE SOLVED: To provide a disk apparatus in which a difference in a transfer rate between the inner peripheral side and the outer peripheral side of a disk. SOLUTION: The magnetic disk apparatus 61 is equipped with a magnetic disk 11 and a flash memory 12. In the magnetic disk 11, sectors of greater sector numbers are allocated to tracks belonging to a zone on the outer peripheral side and sectors of smaller sector numbers are allocated to tracks belonging to the zone on the inner peripheral side. In the flash memory 12, the sector where recording or reading out is performed as the sector of the track on the inner peripheral side is allocated. For example, in the magnetic disk 11, the N<SB>s0</SB>sector is allocated in the zone N<SB>z-2</SB>, the N<SB>s1</SB>sector in the zone N<SB>z</SB>, N<SB>s2</SB>in the zone. In the flash memory 12, the 0 sector is allocated in the zone<SB>z-2</SB>, the N<SB>f1</SB>sector in the zone N<SB>z</SB>, and the N<SB>f2</SB>in the zone N<SB>z</SB>, and N<SB>s0</SB>=N<SB>s1</SB>+N<SB>f1</SB>=N<SB>a2</SB>+N<SB>f2</SB>.
