Disclosed are a system for making 3D contents provided with visual fatigue minimization and a method of the same. The method parses portions of the TOC comprising a series of numbers corresponding to track offsets for each track of the compact disc. One method includes allocating an amount of storage space in the cache to each rank and monitoring a current amount of storage space used by each rank with respect to the amount of storage space allocated to each respective rank. The shift fork changes a gear position of a transmission mechanism. The Agent Apparatus further includes a Type Determining Device for determining the type of the automated function and a Writing Device for writing information representing the type of the automated function in a predefined storage area of a record carrier.
