Abstract
An optical disc player and method reproducing data from an optical disc. The optical disc player may include a data reproducing module irradiating a laser signal onto the optical disc to reproduce a predetermined radio frequency signal corresponding to the data, and a controller determining that a reproduction area of the optical disc is an open session when the data reproducing module reproduces the radio frequency signal having a magnitude less than or equal a predetermined threshold value for a predetermined threshold time. The controller may reproduce the table of contents information recorded in a lead-in area of each session of the optical disc to check the magnitude of a reproduced radio frequency signal so as to determine whether each session is open. As a result, a rapid decision can be made as to whether each session is open to speedily complete a preparation for reproduction and recording from/to the optical disc.
