Abstract
A method includes directing a probe beam to a target that includes an array of data portions in a data storage medium arranged so that a beam area of the probe beam extends across a plurality of adjacent data portions, the array including a data portion subset with each data portion of the subset responsive to the probe beam to produce a response illumination, receiving the response illumination at a detector, and determining data values corresponding to the plurality of adjacent data portions based on the received response illumination. Apparatus and systems are also disclosed.
Claims20
A system, comprising:
- an ionizing radiation beam source situated to produce a modulated ionizing radiation beam and to focus the modulated ionizing radiation beam to a predetermined spot size at an OSL target situated to receive the modulated ionizing radiation beam;
- and
- a scanner situated to produce a movement between the ionizing radiation beam and the OSL target at a scan rate so as to produce a plurality of OSL active data regions in the OSL target corresponding to the scan rate and the modulation of the ionizing radiation beam at a pitch smaller than a read beam area used to access the OSL active data regions.
A method, comprising:
- producing a modulated ionizing radiation beam with an ionizing radiation beam source;
- focusing the modulated ionizing radiation beam to a predetermined spot size at an OSL target;
- and
- scanning the modulated ionizing radiation beam with a scanner to produce a movement between the ionizing radiation beam and the OSL target at a scan rate to produce a plurality of OSL active data regions in the OSL target corresponding to the scan rate and the modulation of the ionizing radiation beam at a pitch smaller than a read beam area used to access the OSL active data regions.
