Abstract
A method of reducing power consumption of a buffer for cache in a tape drive connected to a host in a communicable manner, according to one embodiment, includes detecting a transfer rate of data from the host or to the host, and determining a writing or reading rate of data to or from a tape based on the data transfer rate. A determination is made as to whether predetermined conditions including the data transfer rate, the data writing or reading rate, and a capacity of a buffer are satisfied, where the buffer includes at least two buffer areas. At least one of the buffer areas is selected when the predetermined conditions are satisfied. The selected buffer area is switched to a power saving mode.
