Method and Apparatus for Providing "On Demand" Physical Tape Capacity

Disclosed is a method for providing tape capacity on demand,
allowing a user to upgrade available space on an existing tape in
their library.

With any Tape Storage Product, populate the attached tape
libraries with only the largest capacity tapes. For customers
that don't want to pay for the expense of the High capacity
tapes, we control the amount of usable space on the tape via code
(For example, economy=60G uncompressed, standard=300G, and
High=700). They can later increase the capacity on the existing
tapes by purchasing feature codes that would allow for more space
on the tape. These feature codes could be offered in three forms:
1) Allow the entire library of tapes to change capacity
2) Allow increments of tapes to increase (ie. 100 tape
increments)
3) Allow incremental upgrades by Percent of tape used (start at
50% capacity and increment to 60%, 70% etc.) -It is important to note that over time tape capacities will
increase exponentially, this concept applies to all future tapes.

For example:

Company AAAA purchases a tape library and orders 400 tapes. As
they are on a budget, they only want the lowest capacity tapes.
The product is sold and populated with 400 High capacity tapes
but the customer is charged charge low capacity price. Code only
allows the use of 60G on each tape. As the customer grows and
realizes they need more storage capacity, we sell them 4 feature...
