System controlled RF signal source architecture with transducer near pole-tip for microwave assisted magnetic recording

A method of operating a data storage device, comprising:

• transmitting a control signal for setting a control voltage from a system-on-a-chip (SoC) to a preamplifier;
• in response to the control signal, generating and transmitting the control voltage from the preamplifier to an RF source IC mounted on or near a slider;
• and
• in response to the control voltage and a ground signal transmitted from the preamplifier, setting a frequency and an amplitude of an AC current by the RF source IC and applying the AC current to a transducer that is configured in the slider near a write pole tip of a read/write head, such that the transducer generates a high frequency auxiliary field that is applied to a disk of the data storage device, wherein the read/write head is integrated or mounted on the slider.

One or more processing devices comprising:

• means for transmitting a control signal from a system-on-a-chip (SoC) to a preamplifier;
• means for, in response to the control signal, generating and transmitting a control voltage from the preamplifier to an RF source IC mounted on or near a slider;
• and
• means for, in response to the control voltage, setting a frequency and an amplitude of an AC current by the RF source IC and applying the AC current to a transducer that is configured in the slider near a write pole tip of a read/write head, such that the transducer generates a high frequency auxiliary field that is applied to a disk of a data storage device.
