General Description
1-4 C141-E133-02EN
(12) Automatic alternate block reassignment
If a defective data block is detected during read or write the IDD can automatically reassign its
alternate data block.
(13) Programmable data block length
Data can be accessed in fixed-block length units. The data block length is programmable, and can be
specified at initializing with a multiple of four within the range of 512 to 528 bytes.
(14) Defective block slipping
A logical data block can be reallocated in a physical sequence by slipping the defective data block at
formatting. This results in high speed contiguous data block processing without a revolution delay
due to defective data block.
(15) High speed positioning
A rotary voice coil motor achieves fast positioning.
(16) Large capacity
A large capacity can be obtained from 3.5 type disk drives by dividing all cylinders into several
partitions and changing the recording density on each partition (constant density recording). The disk
subsystem with large capacity can be constructed in the good space efficiency.
(17) Start/Stop of spindle motor
Using the SCSI command, the host system can start and stop the spindle motor.
(18) Diagnosis
The IDD has a diagnostic capability which checks internal controller functions and drive operations
to facilitate testing and repair.
(19) Low power consumption
By using highly integrated LSI components, the power consumption of the IDD is very low, and this
enables the unit to be used in wide range of environmental conditions.
(20) Low noise and low vibration
The noise level is low; approx. 3.9/3.6 bels for MAN series. This makes it ideal for office use.
(21) Microcode downloading
The IDD implements the microcode download feature. This feature achieves easy maintainability of
the IDD and function enhancing.
