Abstract
The coding problem for the binary degraded memory (DM) or write-once-memory (WOM) under a partial modification of records is considered. For this memory, if ´1´ is recorded in any cell then the content of this cell cannot be changed during following recordings. Double recording into such a memory with specified constraints is considered. Upper and lower bounds for the capacity of the DM under this kind of recording are derived. The lower bound is derived only for the case where the size of input messages alphabet is going to infinity.<>
