Character position definition and scope:

A one-character alphabetic code indicates the dimensions of the medium used to encode the electronic resource.  Only the most common dimensions are indicated.  In many cases the dimensions apply to the container in which a magnetic or optical medium is encased.

The field 007/04 code corresponding to the dimensions given in the description of the item are used.  If no code exactly matches the dimensions of the medium (or container), code z (Other) is used.  A fill character ( | ) is used when no attempt has been made to code this position.

Record requirements for National-level and Minimal-level records:  Optional.
