Abstract: According to a positioning method for a hologram in a disk-type holographic storage medium, a guide groove is formed in advance in the disk-type storage medium and is scribed with a positioning marker that includes index information, position information and crossing angle information. The positions of a positioning laser beam and a recording/reproducing laser beam are applied to the same medium position. When an optical head accesses a recording/reading position at a high speed, the shift multiplex recording/reading is performed starting from a marker position. A servo system controls the laser beams to move along the guide groove and ensures that a focused beam is focused on the medium. According to the method, the position and angular information can be quickly positioned in process of performing cross-shift multiplex recording/reading, the recording/reading speed of the system is improved, and random access is achieved.

Abstract: This application discloses a polar code interleaving processing method and apparatus. The method includes: determining N to-be-encoded bits, where N is a positive integer; obtaining a first sequence that includes sequence numbers of N polarized channels, where the first sequence is used to indicate a reliability order of the N polarized channels; performing polar encoding on the N to-be-encoded bits to obtain encoded bits; and performing interleaving processing on the encoded bits based on the first sequence. Because the first sequence used to indicate the reliability of the polarized channels is a sequence already existing in a polar code encoding process, no additional storage resource needs to be used to store the first sequence in the interleaving processing process, thereby reducing use of storage resources.
