Optical disc having tracking polarity information, and apparatuses and methods for recording and reproducing user data on the same

Abstract

An optical disc includes tracking polarity information. The optical disc includes a clamping area, a lead-in area, a data area, and a burst cutting area (BCA). The BCA is present between the clamping area and the lead-in area and in which information regarding the optical disc is recorded, and the information is read before performing tracking in the data area. Accordingly, it is possible to obtain the tracking polarity information and/or reflectivity information without trial and error and directly record or reproduce user data in a data area of the optical disc.

1 . An apparatus for processing data recorded in an information storage medium comprising a first recording layer and a second recording layer, the apparatus comprising: 
 an optical pickup arranged to emit a light to the information storage medium to transfer data with respect to the information storage medium; and    a controller arranged to control the optical pickup to reproduce information regarding the information storage medium from the burst cutting area located in at least one of the first recording layer and the second recording layer,    wherein the information regarding the information storage medium comprises tracking polarity information.    
   
   
       2 . An optical disc, comprising: 
 a first recording layer in which a first lead-in area, a first data area, and a first lead-out area are formed; and    a second recording layer in which a second lead-in area, a second data area, and a second lead out area are formed,    wherein at least one of the first and second recording layers comprise a burst cutting area (BCA) in which information regarding the optical disc is recorded, the information is read before performing tracking in the first and second data areas, and the information regarding the optical disc comprises tracking polarity information.
