Attributes of Micrographics
Advantages Disadvantages
-- relatively low cost -- slow retrieval speed
-- recognized archival medium -- use can cause wear
-- inexpensive reader -- integrity of manual files
-- most cost-effective grayscale storage -- single-user access is a problem
-- accepted as a legal medium -- less than ideal output quality
-- excellent compaction -- resolution loss with
-- standards for creating, succeeding copies
processing, duplicating, storing,
and reading exist

Attributes of Digital Imaging
Advantages Disadvantages
-- excellent record access, distribution, -- relatively high but
and transmission decreasing cost
-- multi-user simultaneous access -- relatively new technology
-- file integrity -- permanent, but not
-- improved quality possible through electronic archival, storage
image processing (restoration and enhancement) medium
-- high-quality printed output -- not yet accepted as
-- no degradation on successive copies legal reproduction
(each copy is as good as the original copy) -- implementation and
-- easily reformatted (cut and paste) operating costs
-- OCR to text possible increase in
-- electronic links to provide retrieval of direct proportion to
individual pages quality of captured
image
(resolution)

Attributes of Optical Disc
Advantages Disadvantages
-- high speed retrieval -- high (but declining) cost
-- longevity 20 years -- relatively expensive
-- preserves file integrity retrieval systems required
-- multi-user access -- not yet cost-effective for
-- no wear during usage (non-contact storage of grayscale page images
read) -- excellent compaction
-- excellent prospects for permanent -- not yet accepted as legal
(not archival) storage document storage medium
