A disk area type detection method and apparatus, the disk area type detection method including detecting the difference between a side push-pull (SPP) 1 signal and an SPP 2 signal; and determining whether an area is a storage medium related information area or a user data area on the disk, based on the detected difference. According to the method and apparatus, the user data area and the storage medium related information area of the disk can be easily distinguished, allowing phase locked loop (PLL) control to be performed appropriately.
