1.2 Hardware Structure
(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. 3.6 Bels Ready for MAS 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.
1.2Hardware Structure
An outer view of the IDD is given in Figures 1.1. The IDD is composed of the disk, head, spindle motor, mounted disk enclosure (DE) with actuator and air circulation filter, as well as read/write pre- amp with the printed circuit assembly (PCA) of the controller.

(1)Disks
The disks have an outer diameter of 70 mm (2.8 inch) and an inner diameter of 25 mm (0.98 inch) for MAS series. The disks are good for at least 20,000 contact starts and stops. Each model contains following number of disks.
MAS3735FC: 4
MAS3367FC: 2
