Health management for magnetic storage media

An apparatus comprising:

• an interface to communicate data with a host;
• a disk of magnetic storage media to store the data;
• a read channel to read the data from sectors of the magnetic storage media;
• a neural network to determine media health scores;
• and
• a media health manager configured to:
• determine, with the read channel, read metrics for a sector of the magnetic storage media from which the data is read;
• determine, from multiple zones of the magnetic storage media, a zone of the magnetic storage media in which the sector resides, each zone of the magnetic storage media corresponding to a respective subset of tracks on the disk of the magnetic storage media;
• access read metrics of the zone of the magnetic storage media, the read metrics of the zone of the magnetic storage media including respective read metrics for the sector from which the data is read and multiple others of the sectors of the zone of the magnetic storage media;
• update the read metrics of the zone of the magnetic storage media based on the read metrics determined for the sector of the magnetic storage media to provide updated read metrics for the zone of the magnetic storage media, the updating of the read metrics comprising updating the respective read metrics of the sector from which the data is read based on the read metrics determined for the sector;
• and
• determine, with the neural network, a health score for the zone of the magnetic storage media in which the sector resides based on the updated read metrics of the zone of the magnetic storage media.

A System-on-Chip (SoC) comprising:

• a pre-amplifier interface to receive signals corresponding to data read from sectors of magnetic storage media;
• read channel logic to process the signals corresponding to the data read from the sectors of the magnetic storage media;
• a hardware-based processor;
• a memory storing processor-executable instructions that, responsive to execution by the hardware-based processor, implement a media health manager to:
• determine, with the read channel logic, read metrics for a sector of the magnetic storage media from which the data is read;
• determine, from multiple zones of the magnetic storage media, a zone of magnetic storage media in which the sector resides, each zone of the magnetic storage media corresponding to a respective subset of tracks on a disk of the magnetic storage media;
• access read metrics of the zone of the magnetic storage media, the read metrics of the zone of the magnetic storage media including respective read metrics for the sector from which the data is read and multiple others of the sectors of the zone of the magnetic storage media;
• update the read metrics of the zone of the magnetic storage media based on the read metrics determined for the sector of the magnetic storage media to provide updated read metrics for the zone of the magnetic storage media, the updating of the read metrics comprising updating the respective read metrics of the sector from which the data is read based on the read metrics determined for the sector;
• and
• determine, with the neural network, a health score for the zone of the magnetic storage media in which the sector resides based on the updated read metrics of the zone of the magnetic storage media.
