发明名称 Method and system for pulsing EAMR disk drives
摘要 A method and system for providing an energy assisted magnetic recording (EAMR) disk drive are described. The disk drive includes a magnetic recording media, a pre-amplifier, an EAMR head, and at least one clock recovery circuit. The pre-amplifier provides a write current signal and a write gate signal for providing power to the EAMR head. The EAMR head includes at least one write transducer and at least one laser. The write transducer(s) are coupled with the pre-amplifier and include at least one writer coil. The write current signal from the pre-amplifier drives the writer coil(s). The clock recovery circuit(s) are coupled with the laser(s). The clock recovery circuit(s) receive the write current signal and the write gate signal and output laser control signal(s) that energize the laser(s) such that the laser(s) are energized synchronously with the writer coil(s).
