Abstract
Storage media such as digital optical disks, PROMS, and paper tape consist of a number of bit positions which initially contain a 'zero' and which can later be irreversibly overwritten with a 'one'. An apparatus and method provide for rewriting in such 'non-erasable memories' for expanding their capacity by allowing the non-erasable memory to be rewritten one or more time.
