Publication number: US20220108715A1
Application number: 17/644,231

Abstract:
The present disclosure generally relates to a magnetic media drive employing a magnetic recording head. The magnetic recording head comprises a main pole, an EAMR stack disposed on the main pole, and a trailing shield disposed on the EAMR stack. The EAMR stack comprises a seed layer disposed on the main pole, a spin torque layer disposed on the seed layer, and a spacer layer disposed on the spin torque layer. At least one surface of the spacer layer in contact with the spin torque layer has a smaller or reduced area than the spin torque layer. The at least one surface of the spacer layer in contact with the spin torque layer is recessed from a media facing surface and has a smaller cross-track width than the spin torque layer and a smaller width in the stripe height direction than the spin torque layer.

Publication number: US20220108745A1
Application number: 17/644,228

Abstract:
The present disclosure generally relates to improved foggy-fine programming. The data can be written to SLC memory. Then, the data can be decoded and then both foggy and finely written to MLC. After the decoding, the data can be stored in DRAM located in a front end or in a SRAM located in a flash manager prior to being written to MLC. After storing in either the DRAM or SRAM, the data is then decoded and written to MLC.

Publication number: US20220100390A1
Application number: 17/643,792

Abstract:
The present disclosure generally relates to methods of operating storage devices. The storage device comprises a controller and a media unit. The capacity of the media unit is divided into a plurality of zones. The controller is configured to make informed use of errors by update zone metadata to indicate one or more first logical block addresses were skipped and to indicate the next valid logical block address is available to store data. The controller is further configured to update zone metadata to recommend to the host device to reset one or more full zones, to recommend to the host device to transition one or more open zones to a full state, to alert the host device that one or more open zones have been transitioned to the full state, and to notify the host device of the writeable zone capacity of each of the plurality of zones.
