Abstract

An apparatus, a computer-readable recording medium, and a method of controlling data recording and reproducing to and from a disk. Controlling the recording of data includes storing password information set in a recording mode and key information to a first area of the disk, encrypting location information of the first area, storing the encrypted location information to a second area of the disk, encrypting desired data and an address of the desired data using the key information, and recording the encrypted data at the encrypted address. Controlling the reproducing of data includes, when the password information is received in a reproducing mode, reading the encrypted location information saved to the second area of the disk, decrypting the encrypted location information of the first area, reading the password information saved to the first area, comparing the received password information with the read password information, and when the received password information is identical to the read password information, reading the key information saved to the first area and reproducing the desired data and the address using the read key information.
