Title:

MECHANICALLY ISOLATED DATA DRIVE DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/227309

Kind Code:

A1

Abstract:

A mechanically isolated data drive device, the mechanically isolated data drive device comprising: a first interface unit, a first control unit, a first magnetic head module, a magnetic medium, a drive structure, a second magnetic head module, a second control unit, and a second interface unit. The first control unit is configured to control the first magnetic head module as a write module when the first interface unit is used as an input interface, and to control the first magnetic head module as a read module when the first interface unit is used as an output interface. The second control unit is configured to control the second magnetic head module as a write module when the second interface unit is used as an input interface, to control the second magnetic head module as a read module when the second interface unit is used as an output interface, and to control the read modules to read data from the magnetic medium and to send the data to the second interface unit. The drive structure is used for driving the magnetic medium to drive, from the write modules to the read modules, the portion in the magnetic medium after magnetic data has been written by the write modules. The security of data drive can be improved.
