Disk storage system having an electronic circuit mounted on the surface of the disk and control method thereof

Abstract

The present invention provides a control method of a rotary storage medium having an electronic circuit that controls connection between an electronic circuit block and an external apparatus to enhance the performance of the entire system, and a system thereof. The system is an intelligent disk system including an intelligent disk having double-surface structure that stores information and is detachable from a drive unit, wherein an electronic circuit is mounted on at least one surface or between both surfaces of the intelligent disk and the electronic circuit is provided with a CPU, and wherein the system controls the intelligent disk so that contents of the disk surfaces of the intelligent disk may be transferred to or loaded in an external apparatus at the time of the intelligent disk rotating or mechanically operating (S 36 -S 37 ) and the CPU may control the external apparatus when the intelligent disk is not operating.

1 . A control method of a rotary storage medium having mounted in one-piece an electronic circuit, including at least a microprocessor, the control method of a rotary storage medium comprising: 
 a step of rotating the rotary storage medium at the time of access to an information recording surface of the rotary storage medium; and    a step of stopping the rotary storage medium except the time of access to an information recording surface of the rotary storage medium to connect said electronic circuit to an external system.    
     
     
         2 . The control method of a rotary storage medium according to    claim 1   , wherein access requests to said information recording surface are queued, and when an access request essential to system operation occurs, the queue requests are executed in a batch mode.  
     
     
         3 . The control method of a rotary storage medium according to    claim 1   , wherein connection between said electronic circuit and said external system is a bus connection in a contact type or a non-contact type.  
     
     
         4 . An intelligent disk system including a storage medium having double-surface structure that stores information and is detachable from a drive unit, wherein an electronic circuit is mounted on at least one surface or between both surfaces of said storage medium and the electronic circuit is provided with at least a microprocessor, and 
 having control means for controlling said storage medium so that contents of information recording surfaces of said storage medium may be transferred to or loaded in an external apparatus at the time of said storage medium rotating or mechanically operating and said microprocessor may control said external apparatus when the storage medium is not operating.
