Abstract: A processing device in a memory sub-system performs a first pass of a multi-pass programming operation to coarsely program a first wordline, performs a second pass to coarsely program a second wordline adjacent to the first wordline, performs a third pass of a multi-pass programming operation to finely program the first wordline, performs a fourth pass of a multi-pass programming operation to coarsely program a third wordline adjacent to the second wordline, performs a fifth pass of a multi-pass programming operation to finely program the second wordline, and responsive to determining that at least the second wordline has been finely programmed, performs a read verify operation on one or more cells associated with the first wordline.

Abstract: Exemplary methods, apparatuses, and systems include receiving an instruction to atomically write data to a memory component. A plurality of write commands for the first data are generated, including an end of atom indicator. The first plurality of write commands are sent to the memory component while accumulating a plurality of translation table updates corresponding to the write commands One or more translation tables are updated with the plurality of translation table updates in response to determining that the final write command has been successfully sent to the memory component.

Abstract: Embodiments of optical disc drives are described that perform automatic forward sense calibration of write laser power using a sample and hold sampling strategy that is automatically determined based on an automatically selected write strategy. Embodiments of the described optical disc drive may be dynamically configured to support any optical disc media, any write mode, and any write strategy. The write strategies supported may include dynamically changing write speeds and/or write power levels across the respective optical media tracks. As the optical drive is automatically configured for a selected write media/write mode/write strategy, the sample and hold sampling delays used to control the sampling of a forward sense feedback signal are also automatically configured, thereby allowing each forward sense sampling point to be aligned with an area of the forward sense feedback signal that corresponds to a power level of interest and that avoids distortion in the feedback signal.

Abstract: An approach is described that allows an optical disc drive to accurately verify the power level of irradiation beam power levels associated a write strategy used in high speed, high density optical disc media formats using a front monitor diode with a relatively slow rise time and/or relative slow fall time compared to the clock cycle speed of the write strategy signal. A portion of encoded data to be written to an optical disc media may be overwritten to include a predetermined data pattern. During write strategy processing of the data, the predetermined data pattern is replaced with a constant write strategy power level. The constant write strategy output placed within the write strategy signal may control the optical disc drive laser to emit a constant irradiation beam for a duration sufficiently long to allow the front monitor diode to obtain an accurate measure of the irradiation beam power level.

Abstract: Circuits, architectures, systems, methods, software, and algorithms for detecting a modulation transition (e.g., a change from a written portion containing RF-modulated data to an unwritten portion containing only a wobble signal modulation) on an optical storage medium. The method generally includes steps of focusing a first spot of light onto an optical storage medium, wherein the first spot is substantially centered on a first track of the optical storage medium, focusing a satellite spot of light onto an optical storage medium, wherein the satellite spot at least partially overlaps a track adjacent to the first track, generating a satellite signal from light reflected from the optical storage medium from the satellite spot, and detecting the modulation transition by detecting a change in a level of the satellite signal.

Abstract: A system and method of laser bias control in optical recording media applications are disclosed. In some implementations, bias control for output power may be based upon a detected ratio of erase power to write (or peak) power, i.e., the Pe/Pw (or Epsilon, ?) ratio.
