THREE DIMENSIONAL OPTO-MAGNETIC DATA STORAGE SYSTEM AND METHOD

摘要

The present invention relates to a data storage system and a method which has high storing capacity and high data access rate and low power consumption. The said data storage system essentially includes at least two optical layers, and which have at least one active layer in which the light is generated, at least one lower electric contact enabling the electric energy to be transferred to the active layer and at least one upper electric contact, at least two reflecting layers reflecting the light generated in the active layer; at least one thermal insulator; at least one magnetic layer, which has at least one storage bit, at least one lower buffer bit, at least one upper buffer bit enabling the data to be transferred up; at least one transparent layer and transfers the light generated by the optical unit to the magnetic layer.

1. A three dimensional opto-magnetic data storage system comprising:
at least two optical layers which enable the circularly polarized light required for recording data to be generated, which further comprises:
at least one active layer in which the light is generated,at least one lower electric contact enabling the electric energy to be transferred to the active layer and having a circular shaped hole at the center to allow the light to pass,at least one upper electric contact enabling the electric energy to be transferred to the active layer,at least two reflecting layers reflecting the light generated in the active layer; at least one thermal insulator which prevents the heat transfer between two adjoining optical layers; at least one magnetic layer which is manufactured from a ferromagnetic material suitable for opto-magnetic recording, which comprises at least two storage bits and at least one upper buffer bit enabling the data to be transferred up, and at least one lower buffer bit enabling the data to be transferred downward therein; at least one transparent layer which is located on the magnetic layer and transfers the light generated by the optical unit to the magnetic layer; at least one top layer which comprises at least two optical units arranged side by side so as to have space in between each other at least one thermal insulator present in the space between the optical units, and at least one magnetic layer located on the plane formed by the optical units and the thermal insulator; at least one intermediate layer which is located under the top layer comprises at least two optical units arranged side by side so as to have space in between each other, at least one thermal insulator present in the space between the optical units, at least one magnetic layer present on the plane formed by the optical units and the thermal insulator, and at least one transparent layer present on the magnetic layer; at least one bottom layer which is located under the intermediate layer, comprises at least one magnetic layer and at least one transparent layer located on the magnetic layer.
