| is
a flat film format the same size as a jacket but with the advantage
of having up to 420 images on one sheet. Filming is a direct
process and therefore normally necessitates a duplicate which
would become your working copy. |
| This format is also compatible with COM (computer
output microfilm) as similar reduction ratios can be used. |
A
microfilm jacket, usually used in a personnel type application,
provides an individual record of up to 60 A4 documents in a
polyester laminate, 105 x 148mm postcard size, with record identification
along a strip at the top of the jacket. The main advantage a
jacket format is that it is a unitised record, like a paper
file it can added to or edited at any time. |
| A jacket system has all the advantages of
a conventional paper file plus all the benefits that microfilm
can add. The jacket format is also used where a mix of documents
and drawings are held in one file, i.e., planning applications
or contract files, and in this instance 3 drawings and 36 documents
are held within the jacket. |
