INDEXING BLOCKS OF DATA
-------------
An index should be established for each cassette to tell the user how many
blocks of information are on the cassette and what is contained in each block.
The following are suggested methods to index a cassette.
r-Aa s ter Li st
1. Use a looseleaf binder,
ledger,
etc., for a master
list.
2. Assign each cassette a control number.
3. Record cassette number and contents of cassette
by
"Block" number on the
master list.
Index Card
1. Use a 3 x 5 card or a
card
that
can
fit in the cassette container.
2. Record contents of cassette
by
block number.
3. Keep card with cassette at all times.
Index On Tape - If the index is long or detailed, it may be advantageous to
put the index on tape.
1. Reserve the first "Block" on the cassette for the index. The amount of tape
to be reserved for the index "Block"
should
be estimated according to the
anticipated size of the index. The following factors could be used as a
rough
guide
to
estimate the
tape
required:
A) A large index could take a full page
(Bt
x 11") which would be
approximately
2500 characters.
B)
Advancing the
tape
5
characters.
seconds would give you space to "Write" 2500
2. Enter the index in the first "Block" as the other "Blocks" of information
accumulate.
3. When you need information from that cassette, print out the
index block to
determine what is on that cassette and the block number that contains the
desired information.
