Fujitsu MAG3091FC, MAF3364FC Programmable data block length, Defective block slipping, Diagnosis

(14)Programmable data block length

Data can be accessed in fixed-block length units. The data block length is programmable, and can at initializing with a multiple of four for the 512 to 528 bytes.

(15)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.

(16)High speed positioning

A rotary voice coil motor achieves fast positioning.

(17)Large capacity

A large capacity can be obtained from 3-inch 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.

(18)Start/Stop of spindle motor

Using the SCSI command, the host system can start and stop the spindle motor.

(19)Diagnosis

The IDD has a diagnostic capability which checks internal controller functions and drive operations to facilitate testing and repair.

(20)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.

(21)Low noise and low vibration

The noise level is low: Approx. 4.2 bels for the MAF3364FC and 4.0 bels for the MAG series. This makes it ideal for office use. The IDD has rubber vibration isolators, which minimize the transfer of vibration.

(22)Microcode downloading

The IDD implements the microcode download feature. This feature achieves easy maintainability of the IDD and function enhancing.
