Tape data storage cartridge with memory

摘要

A tape data storage cartridge which includes a memory device for storing a position of the last data recorded on the tape to facilitate data retrieval comprises: a casing 200; a data storage medium 100; a memory device 416; wherein said memory device may be configured to store data identifying a location of an end 114 of a last user data written onto said medium; and said data, indicating said last user data, is stored in said memory device before it is written to said medium at location on said medium 100 after said user data. In a further mode of operation, data identifying a location of one or a plurality of successfully written data sets which have already been written to a data storage medium are stored in a memory device within the casing of the tape data storage cartridge, whilst further write operations of user data are written to the data storage medium. <IMAGE>
