Disk reference surface, Error correction code | Fujitsu MCM3064AP

Glossary

Disk reference surface

An ideal flat ring surface of an ideal spindle that comes into contact with the clamp area on a disk. The disk reference surface is perpendicular to the rotation axis.

Error correction code

An error correction code designed to correct specific errors in data.

Error detection and correction

A series of methods used to add a redundant code to data in the existing format and then record data. In read mode, the decoder removes a redundant code and detects and corrects errors using the redundant information.

Interleaving section

A process that physically arranges data units so that data resists burst errors.

LUN (Logical Unit Number)

A device address used to identify a logical unit.

Recording layer

A disk layer in which data should be recorded during manufacturing or recording.

Recording power

An incidence power specified on the incidence surface and used to form marks.

Sense code

A single-byte code set in sense data. This information is used to identify the type of error detected.

Sense data

Information generated by the target to report detailed error information if a command end status contains any error information.

Sense key

A 4-bit code set in sense data. This information is used to classify the type of error detected.

Spindle

A disk drive component that comes into contact with a disk and a hub.
