Abstract: In a flat-conductor connector having an automatic lock mechanism for a flat conductor, a fitting connection operation of a flat conductor is enabled to be reliably performed again after the flat conductor is extracted. A flat-conductor connector 1 includes a lock member including a slip-off stop locking surface configured to pass through a flat conductor housed in a housing chamber of a housing in the thickness direction of the flat conductor and lock the flat conductor. The lock member includes a supporting portion configured to support the slip-off stop locking surface so as to be displaceable between a locking position at which the lock member is locked with and stops the flat conductor from slipping off and a lock cancellation position at which the lock member is unlocked from the flat conductor to cause the flat conductor to be extractable from the housing chamber.

Abstract: A data storage device may comprise a disk comprising a plurality of zones, each comprising a plurality of data tracks, a head having a reader spaced away from a writer by a gap, and a controller. The controller may be configured to, upon detecting a media defect in one of the zones: determine a width of data tracks in the zone in which the media defect is detected; calculate a minimum number of contiguous tracks in the zone in which the media defect is detected whose aggregate width is at least as great as the gap between the reader and writer; and margin the detected media defect with a number of tracks immediately adjacent to the detected media defect that is at least equal to the calculated minimum number of contiguous tracks.
