Disk reference surface

Glossary

Disk reference surface

An ideal flat ring surface of an ideal spindle that is in contact with the clamp area on the disk. It 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 data by adding a redundant code to data in the existing format. In read mode, the decoder removes a redundant code and detects and corrects errors using 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 layer on the disk on which data is recorded at production or recording .

Recording power

An incidence power specified on the incidence surface. Used to form marks.

Sense code

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

Sense data

Information generated by the target to report detailed error information if any error information is contained in the command end status.

Sense key

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

Spindle

A component of the disk drive unit that is in contact with the disk and hub.
