Abstract
Described are optical magnetic recording systems, writers, media, and methods that utilize pulses of electromagnetic radiation to deterministically record information on magnetic storage media unaided by any additionally applied magnetic field such as from a write pole. The recording pulses may be linearly (or longitudinally) polarized pulses or circularly polarized pulses. The pulses may be modulated in accordance with data bits to be written on the media. Modulation may include modulating the polarization state(s) of the pulses and/or modulating the amplitude(s) the pulses, depending on the particular construction or configuration of the magnetic storage media to be used. Described are recording systems and methods that include laser light pulse generation, light pulse modulation, light pulse delivery, and magnetic media constructions.
