<p>Data reproducing apparatus includes a machine readable store (13) to contain blocks of data, such as video games programmes, to be reproduced. The data is reproduced onto a portable data carrier such as a cassette containing 'Flash EPROM'. The reproducing apparatus has controls to initiate a copying transaction to copy a selected programme onto the cartridge, or an erase operation to erase a previously copied programme from the cartridge. A record of all copying transactions is recorded in RAM and this record includes data uniquely correlating the stored transaction record and the respective data carrier onto which date has been reproduced. When the data carrier is to be erased, the appropriate transaction record that correlates with the carrier is identified and the record is updated to show that the particular copy has been erased.</p> |
