    Abstract: A system for sending and receiving data and detecting data errors for correction which includes means for detecting an error in data as it is read from a tape or like device and means for forwarding the data with the error into a further storage point in the system where it is stored for a first time. A second cycle or storage of the data with the error in the storage point is called for, the data with error being arranged to distinguish it from the arrangement of the error data as it existed at the first time at the storage point. The two versions of the same data having error therein are compared to detect and correct the data in error.

    Abstract: A container for a record member of the flexible web type which includes a box having one wall hinged to provide an openable cover. A single reel may be journaled for free rotation on an axis parallel to the plane of the cover wall. The record member is wound on the reel with its inner end firmly secured to the reel and its outer end firmly secured to the cover at a point spaced from the hinged edge of the cover. Other means of web retention may be used. Drive connection means for the reel are provided through the container to permit the record member to be reeled or unreeled as required while the ends remain secured. The invention also includes the combination of the container with a record handling system having a processing chamber into which the portion of the member intermediate its ends may be inserted.
