Microfilm or Digitization: Simplified View (Continued…)

This is in continuation to my earlier article “Microfilm or Digitization: Simplified View”. In earlier article I discussed why digitization should be preferred over Microfilms, although microfilms have certain advantages over digitization like life expectancy of microfilm is of 500 years, it is eye readable and is also an analog technology.

In today’s scenario digitization has proved itself over the advantages of microfilms; for e.g. storage media cost is cheap today and transfer of data from one media to another (in case of technology upgradation) is also simple or automatic. Scanned/digitized images cannot be read through naked eye from the storage media directly (without attaching it to a computer system) but a computer system is now available at every corner of the globe and is rapidly expanding its reach.

Below is the comparison of Digitization and Microfilming/Scanning to understand the concept in detail.

Sl. No Activities Microfilm Scanning
(A)   COST    
1 Cost of conversion More than scanning Less than Microfilms
2 Space Requirement More (As physically stored) Less (As electronically stored)
3 Preservation / Storage Method Special Physical method Virtual / Electronic
4 Maintenance Method Special Physical method Virtual / Electronic
5 Technology Refreshing Cost High Low
6 Effect of environmental changes Sensitive (Because it is tangible) Insensitive (Non tangible)
7 Security Procedures Special Physical method Virtual / Electronic
8 Transfer / transportation cost More (Physical) Less (Electronic)
       
(B) TECHNOLOGY    
1 Physical damage Possible Not possible
2 Technological essence Outdated Latest
3 User acceptance Not user friendly User friendly
4 Document Sharing Not possible Possible
5 Rapid Retrieval Takes more time Quick
6 Concurrent Access Not possible Possible
7 Access Method Sequential & Physical(Time consuming) Random (Quick)
8 Retrieval Method Requires special device By basic Computer
9 Query resolution based on documents Takes more time Instantaneous
10 Remote Access (Across world) Not Possible (As it is physical) Easily possible (As it is electronic)
11 Online Access (Network, Internet etc.) Not possible Easily possible
12 Viewing Images Requires special device By Click of mouse
13 Printing Poor image & delayed Good Image & quick
14 Reproducing Images Limited Unlimited
15 Alternate to Photocopy Costly Method (Physical) Economical Method (Digital)
16 Alternate to printing Costly Method (Physical) Economical Method (Digital)
17 Workflow compatibility by software Not possible Possible
18 Software Integration (Document Mgt.) Difficult Easy
19 Sensitivity to light More Insensitive (Non tangible)
20 Method to View Requires special device On Any Computer
21 Magnification Percentage Limited Unlimited
22 Inter Office Movement of records Physical (First Printing then Hand carried) By Computer Network
       
(C)  QUALITY    
1 Quality Control Requires close monitoring Easy
2 Color digitization Poor Quality Good Quality
3 Image Enhancement Not possible Possible
4 Conversion / Duplication Quality degrades Remains same
5 Visual clarity of images Can’t see by naked eye Visible through naked eye
6 Optical Character Recognition Not Possible Possible
7 Rearranging captured sequence Not possible Possible
