The disc rotating direction control method comprises the steps of: receiving a trigger signal; generating a driving pulse according to the trigger signal; and sending the driving pulse to a spindle driver so that a spindle driver can control the rotating direction of a spindle motor according to the driving pulse, wherein the spindle motor is used for driving discs to rotate. The embodiment of the invention can control the rotating direction of discs, effectively lower the disc resonance and reduce the disc vibration, thereby realizing the purpose of disc protection.

The invention relates to a graphene-based magnetic adjustable Faraday rotator. The structure is composed of three portions, i.e., a circular waveguide applied to a microwave frequency range, a multilayer graphene module vertical to a microwave signal propagation direction in the circular waveguide, and a solenoid module sleeving the circular waveguide for providing magnetic field offset. The multilayer graphene module is composed of multiple single-layer graphene sheets in parallel arrangement inside the module. The solenoid module can control the strength of an externally added bias static magnetic field through controlling the size of currents. When electromagnetic waves in a TE11 mode, transmitted inside the circular waveguide, are transmitted through the graphene module under a condition with the magnetic offset, angle deflection is generated. By using the rotator, a rotation angle can be accurately adjusted within a certain scope. Besides, the Faraday type rotator also has the advantages of simple and compact structure, quite small size, easy integration, simple control, and convenient use.
