When a capillary network device connects to user equipment and the user equipment establishes or modifies a bearer to support traffic from the capillary device, the user equipment may request that the network provide some indication that the user equipment will not be charged for the traffic. The present invention utilizes defect processing table to reduce the seek times of a pick-up head in obtaining replacement ECC blocks for defect ECC blocks in a user data area of the disc. To these conventional characteristics are added additional characteristics known as indicators which are derived from an analysis of the usage of the system by users.
