(*1)

The formatted capacity can be changed by changing the logical block length and using spare sector

space.

See Chapter 3 for the further information.

(*2)

The number of user cylinders indicates the max., and includes the alternate cylinder.

The number

of user cylinders and alternate cylinders can be specified at format of the IDD.

(*3)

The positioning time is as follows:

(*4)

The start time is the time from power on or start command to when the IDD is ready, and the stop

time is the time for disks to completely stop from power off or stop command.

(*5)

This value indicates at ready mode.

(*6)

Up to 4 SCSI devices having capacitance of 25pF or less can use cable length of up to 3.0 m.

(*7)

5 to 8 SCSI devices having capacitance of 25pF or less can use cable length of up to 1.5 m.

(*8)

1 on 1 connection case.

(*9)

1 host, 15 devices case.

(*10)

The maximum data transfer rate may be restricted to the response speed of initiator and by

transmission characteristics.

(*11)

The terminator power pin (SCSI connector) which supplies power to other terminators is not used.
