Abstract:
A method for recording data at variable speeds onto a magnetic tape that is being transported across a rotating drum at a current tape transport speed, said rotating drum having a recording head disposed thereon to pass over said tape upon rotation of said drum, said data being received from a host system and temporarily stored in a data buffer, said method comprising:monitoring a current buffer level of said data buffer, said current buffer level indicating an amount of data currently present in said data buffer;determining a new tape transport speed based on said current buffer level;writing a first predetermined number of dummy tracks onto said magnetic tape at said current tape transport speed;adjusting said current tape transport speed to said new tape transport speed; andwriting a second predetermined number of dummy tracks onto said magnetic tape at said new tape transport speed immediately after said first predetermined number of dummy tracks;wherein said current tape transport speed and said new tape transport speed are each non-zero and different from one another.
