A tape drive method and apparatus is disclosed wherein payload data is sent from a host computer device to a tape drive data storage device in data block sizes which are specified by the host computer, for example in the case of a tape drive presenting a CD-ROM image, in 2 kbyte blocks, whereas the tape drive writes to tape media in an optimal block size required to keep the tape media streaming across the tape heads, for example 8 kbyte blocks. Conversion between block size is achieved by buffering incoming payload data in a buffer, and by reading or writing to the tape media in the optimum block size.
