The Frame Ground is shorted in the optical disk drive by a metal strip attached to the vibration
isolation rubber between the frame (FG) and the base (SG).

Power Supply Requirements
(1)
Allowable input voltage and current
The DC power supply input voltage measured at the power supply connector pin of the optical
disk drive (receiving end) must satisfy the requirements in Section 2.1.3. (For other
requirements, see items (4) and (5) below.)
(2)
Current waveform (reference)
Figure 3.8 shows the +5 VDC waveform at start of spindle motor rotation.

Current waveform (+5 VDC)
(3)
Power on/off sequence
a) In a system which uses the terminating resistor power supply signal (TERMPWR) of the
SCSI bus, the requirements for +5 VDC given in Figure 3.9 must be satisfied between the
drive and at least one of the SCSI devices supplying power to that signal.
