Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 360: Dynamic Magnetic Information Storage Or Retrieval

This class is an integral part of Class 369, Dynamic Information Storage or Retrieval, and is the specific class for apparatus and corresponding processes for the storage and retrieval of information based on relative movement between a magnetic record carrier and a transducer. It includes apparatus and corresponding processes for making copies or editing of records falling within the above definition. A magnetic record carrier within the meaning of this class is an element which consists of a magnetizable material or is comprised of a coating or impregnation of magnetizable material which is intended for the storage of more than a single bit of information.

Subclass 98.08: Seating of disks
Subclass 99.12: Disk seating

Class G9B/17.012:


Class G9B/25.003:


Class 720: Dynamic Optical Information Storage Or Retrieval

This is the specific class for apparatus and corresponding processes for the storage and retrieval of variable optical or magneto-optical information based on relative movement between an optical storage carrier or medium and a transducer along a continuous path. It includes apparatus and corresponding processes for making copies or editing of optical records falling within the above definition, and also includes the record carrier or medium, per se, having particular information storage structure.

Subclass 632: Transferring mechanism
Subclass 725: Disk cartridge

Class 369: Dynamic Information Storage Or Retrieval

Apparatus for the storage or retrieval of arbitrarily variable information which is retained in a storage medium by variation of a physical characteristic. The information is stored or retrieved by causing or sensing a variation of a physical characteristic of the storage medium by a transducer having relative motion along a continuous path.
