Title: Method for controlling buffer and drive
Inventor: WATABE TOSHIYUKI
IPC: G06F3/06
Filed: 1991-09-11
Abstract: PURPOSE:To shorten the waiting time caused by the start of a drive by using effectively a buffer provided between the drive and a host computer. CONSTITUTION:A control part 43 receives a read instruction from a host computer 41 and decides whether the read data are stored in a buffer 42 or not. If not, a read instruction if issued to a drive (magnetic tape device) 44. Thus the drive 44 is started and carries out the input of data. If the read data are present in the buffer 42, a fact whether the read data is present in the direction to be read or not. If not, the data are inputted from the drive 44. If so, the buffer 42 starts to send the data to the computer 41. Thus the state of the buffer 42 and the read data are effectively used so that the waiting time can be extremely shortened to the start end of the drive 44.
