This section describes the drive mechanism. Section 5.2 describes the drive
electronics. The Quantum Fireball Plus AS hard disk drives consist of a mechanical
assembly and a PCB as shown in Figure 5-1.
The head/disk assembly (HDA) contains the mechanical subassemblies of the
drive, which are sealed under a metal cover. The HDA consists of the following
components:
• Base casting
• DC motor assembly
• Disk stack assembly
• Headstack assembly
