A DVD reproducing apparatus includes a pickup to read data from a disk having a pit data area to form pits along tracks and an NBCA to read data by laser cutting in a radial direction, a tracking error signal generator to generate a tracking error signal, an RF signal generator to process a signal output from the pickup to generate an RF signal, an NBCA data demodulator to employ the RF signal to demodulate data recorded in the NBCA, a jump controller to permit the pickup to jump over the tracks based on the tracking error signal, and a sled motor to move the pickup in the radial direction. Preferably, the jump controller applies a predetermined voltage to the sled motor, sets a time length to apply the predetermined voltage, and moves the pickup from the NBCA to the pit data area by single driving of the sled motor.
