Device Configuration

2.1 Device Configuration

Figure 2.1 shows the disk drive. The disk drive consists of a disk enclosure (DE), read/write preamplifier, and controller PCA. The disk enclosure contains the disk media, heads, spindle motors, actuators, and a circulating air filter.

Figure 2.1 Disk drive outer view

(1) Disk

The outer diameter of the disk is 65 mm. The inner diameter is 20 mm.

(2) Head

The heads are of the load/unload (L/UL) type. The head unloads the disk out of while the disk is not rotating and loads on the disk when the disk starts.

(3) Spindle motor

The disks are rotated by a direct drive Sensor-less DC motor.

(4) Actuator

The actuator uses a revolving voice coil motor (VCM) structure which consumes low power and generates very little heat. The head assembly at the edge of the actuator arm is controlled and positioned by feedback of the servo information read by the read/write head. If the power is not on or if the spindle motor is stopped, the head assembly stays on the ramp out of the disk and is fixed by a mechanical lock.

(5) Air circulation system

The disk enclosure (DE) is sealed to prevent dust and dirt from entering. The disk enclosure features a closed loop air circulation system that relies on the blower effect of the rotating disk. This system continuously circulates the air through the circulation filter to maintain the cleanliness of the air within the disk enclosure.

MHV2040AH, MHV2080AH, MHV2060AH, MHV2100AH specifications

The Fujitsu MHV series of hard disk drives, specifically the MHV2060AH, MHV2080AH, MHV2100AH, and MHV2040AH, are renowned for their reliability and performance in the mobile HDD segment. Designed primarily for use in laptops and other portable devices, these drives integrate cutting-edge technologies to meet the demands of today's data-intensive applications.

One of the hallmark features of the MHV series is its high data density, allowing for substantial storage capabilities in compact sizes. The MHV2060AH offers a storage capacity of 60 GB, while the MHV2080AH and MHV2100AH offer 80 GB and 100 GB respectively. The MHV2040AH provides a slightly more modest but still robust 40 GB of storage. This range of capacities ensures that users can select the model that best fits their storage needs.

The drives utilize the latest perpendicular magnetic recording (PMR) technology, which enhances recording efficiency and increases data storage densities. This technology significantly optimizes the use of disk surface area, providing better performance and more reliable data access. Additionally, the MHV series incorporates an advanced actuator system that ensures precision head positioning, enhancing data integrity and reducing error rates during read and write operations.

In terms of performance, the MHV series maintains a revolutions per minute (RPM) rating of 5400, which strikes a balance between speed and energy efficiency, making these drives suitable for low-power applications. The drives are also designed with a low acoustic level, generating minimal noise during operation—a crucial factor for mobile users who prefer quieter devices.

Furthermore, the Fujitsu MHV series features a robust shock resistance design, allowing them to withstand the rigors of mobile computing. This makes them suitable for use in portable environments subject to vibration and physical movement, thus ensuring data security and drive longevity.

Overall, the Fujitsu MHV2060AH, MHV2080AH, MHV2100AH, and MHV2040AH represent a formidable selection of mobile hard disk drives filled with advanced technologies and features, making them well-suited for a wide range of applications in today's fast-paced digital world. With their combination of storage capacity, performance, and durability, these drives continue to serve as reliable solutions for users seeking efficient data storage in portable formats.
