  • Patent number: 10082545
    Abstract: In general, techniques of this disclosure are directed to a sensor for measuring an external magnetic field. The sensor an optical cavity, a laser medium which together with the optical cavity has a laser threshold, a laser pump, and a radio-frequency (RF) drive applied to the laser medium, such that the laser threshold varies with a change in the external magnetic field. The RF drive may be applied to the laser medium at or around a particular resonance frequency which varies depending on the external magnetic field, such that depending on the value of the external magnetic field, the RF drive induces transitions between at least two states of the laser medium, each state causing a different laser threshold in an intensity of a laser output. Further, the intensity of the laser output may provide a measurement of the value of the external magnetic field.

  • Patent number: 10056146
    Abstract: The system includes a data storage medium comprising cells, an excitation circuit, and an emitter. The cells arranged in a three dimensional space. The excitation circuit excites each cell independently. Exciting a cell changes an optical property of the cell. The emitter emits a first beam onto a first cell during a first excitation period to orient electrical charges within the first cell to a first oriented value and intensity of electric field to a first intensity value. The emitter emits a second beam onto a second cell during a second excitation period to orient electrical charges within the second cell to a second oriented value and intensity of electric field to a second intensity value. The first and second cells maintain the first and the second oriented values and the first and second intensity values after the first and second excitation periods are over, respectively.

The apparatus includes an array of probes that is arranged in a predetermined pattern, such as a servo pattern. The array of probes is brought into contact, or near-contact, with a magnetic recording medium that has been bulk erased substantially along an initialization direction. Each probe is energized so as to heat its respective contacted (or near-contacted) region of the recording medium above a threshold temperature. An external magnetic field is applied to the heated regions in a direction that is substantially opposite from the initialization direction. The strength of the external magnetic field is chosen to be greater than the coercivity of the recording medium at the threshold temperature, but less than the coercivity of the recording medium at room temperature. As a result, only magnetizations in the heated regions become aligned with the external field.

    Abstract: An optical information recording medium 10 comprises a plurality of recording layers 14, and intermediate layers 15 each provided between the recording layers 14. Each of the recording layers 14 includes polymer binder and dye dispersed in the polymer binder, and the dye is subject to multi-photon absorption of a recording beam RB having a predetermined wavelength and to linear absorption not smaller than 1.5% per recording layer at the predetermined wavelength of the recording beam. When the dye is irradiated with the recording beam and generates heat by linear absorption and multi-photon absorption of the recoding beam RB, the polymer binder undergoes a change of shape by the generated heat, whereby an interface between the recording layer 14 and the intermediate layer undergoes a change of shape to record information.
