Mini CD Description

With the decline in the use of Microfiche as a viewing medium, the P.R.T. Society has resolved to publish all new material in the form of Pdf files on CD’s.

Existing publications on Microfiche will remain available until existing stocks are exhausted.

All existing publications will eventually be converted to and sold in Pdf format.

To enable us to keep prices and costs to a minimum, the society has resolved to use the smallest and most economical medium to publicise it’s transcripts, this is in the form of the Mini CD, (3½”/80mm), which has less storage capacity, 180MB, compared to 700MB+ for normal CD's.

The Mini Cd is exactly the same as a normal CD, except it is physically smaller and has a smaller storage capacity, (180MB). The Mini CD fits into normal CD Drives into the centre recess as indicated below.

These are supplied in plastic envelopes, not plastic cases and require less postage and packing.
