Abstract:
A method for making an information processing apparatus with multitasking functions, comprising the steps of:(a) providing a plurality of turntables, each rotatable about a respective one of central axes for detachably mounting at least one disc thereon; (b) affording a plurality of head units each having a driving means and a head-means group, each of said driving means being arranged for moving a respective one of said head-means groups in a direction perpendicular to at least one of said central axes, and each of said head-means groups being adapted to comprise at least one optical head means each for interacting with a disc surface; (c) decoding a set of encoded information retrieved by one of said optical head units; (d) encoding a set of information to be stored through another one of said head units; and (e) simultaneously controlling said plurality of head units, so as to process at least said set of encoded information and said set of information to be stored in multitasking.
