1.5 Seek time
Seek measurements are taken with nominal power at 25°C ambient
temperature. All times are measured using drive diagnostics. The spec-
ifications in the table below are defined as follows:
•Track-to-track seek time is an average of all possible single-track
seeks in both directions.
•Averageseektimeisatruestatisticalrandomaverageofat least5,000
measurements of seeks between random tracks, less overhead.
•Full-stroke seek time is one-half the time needed to seek from the first
data cylinder to the maximum data cylinder and back to the first data
cylinder. The full-stroke typical value is determined by averaging 100
full-stroke seeks in both directions.
Note. These drives are designed to consistently meet the seek times rep-
resentedin this manual. Physicalseeks,regardless ofmode (such as
track-to-trackandaverage)areexpectedtomeetorexceedthenoted
values.However, duetothemannerinwhich these drivesareformat-
ted, benchmark tests that include command overhead or measure
logicalseeksmay produce resultsthatvaryfromthesespecifications.

drive power connector.

1.7.1 Power consumption
Power requirements for the drives are listed in the table on page 9.
Typical power measurements are based on an average of drives tested,
under nominal conditions, using 5.0V input voltage at 25°C ambient
temperature.
•Spinup power
Spinup power is measured from the time of power-on to the time that
the drive spindle reaches operating speed.
•Seek Mode
During seek mode, the read/write actuator arm moves toward a
specific position on the disc surface and does not execute a read or
write operation. Servo electronics are active. Seek mode power rep-
resents the worst-case power consumption, using only random seeks
with read or write latency time. This mode is not typical and is provided
for worst-case information.
•Read/Write power and current
Read/write power is measured with the heads on track, based on a
16-sector write followed by a 32-msec delay, then a 16-sector read
followed by a 32-msec delay.
•Operating power and current
Operating power is measured using 40 percent random seeks, 40
percent read/write mode (1 write for each 10 reads) and 20 percent
drive inactive.
•Idle mode power
Idle mode power is measured with the drive up to speed, with servo
electronics active and with the heads in a random track location.
•Standby mode
During Standby mode, the drive accepts commands, but the drive is
not spinning, and the servo and read/write electronics are in power-
down mode.

Input noise ripple is measured at the host system power supply across
an equivalent 80-ohm resistive load on the +12 volt line or an equivalent
15-ohm resistive load on the +5 volt line.
•Using 12-volt power, the drive is expected to operate with a maximum
of 200 mV peak-to-peak square-wave injected noise at up to 10 MHz.
•Using 5-volt power, the drive is expected to operate with a maximum
of 150 mV peak-to-peak square-wave injected noise at up to 10 MHz.
Note. Equivalent resistance is calculated by dividing the nominal volt-
age by the typical RMS read/write current.
1.7.3 Voltage tolerance
Voltage tolerance (including noise): 5V ± 5% and 12V ± 10%
1.7.4 Power-management modes
The drive provides programmable power management to provide great-
er energy efficiency. In most systems, you can control power manage-
mentthroughthesystemsetupprogram.Thedrivefeaturesthefollowing
power-management modes:
•Active mode
The drive is in Active mode during the read/write and seek operations.
•Idle mode
The buffer remains enabled, and the drive accepts all commands and
returns to Active mode any time disc access is necessary.
•Standby mode
The drive enters Standby mode when the host sends a Standby
Immediate command. If the host has set the standby timer, the drive
can also enter Standby mode automatically after the drive has been
inactive for a specifiable length of time. The standby timer delay is
established using a Standby or Idle command. In Standby mode, the
drive buffer is enabled, the heads are parked and the spindle is at rest.
Power Modes Heads Spindle Buffer
Active Tracking Rotating Enabled
Idle Tracking Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled

U Series 5 Family Product Manual, Rev. B 11
The drive accepts all commands and returns to Active mode any time
disc access is necessary.
•Sleep mode
The drive enters Sleep mode after receiving a Sleep command from
the host. In Sleep mode, the drive buffer is disabled, the heads are
parked and the spindle is at rest. The drive leaves Sleep mode after
it receives a Hard Reset or Soft Reset from the host. After receiving a
reset, the drive exits Sleep mode and enters Standby mode with all
current translation parameters intact.
•Idle and Standby timers
Each time the drive performs an Active function (read, write or seek),
the standby timer is reinitialized and begins counting down from its
specified delay times to zero. If the standby timer reaches zero before
any drive activity is required, the drive makes a transition to Standby
mode. In both Idle and Standby mode, the drive accepts all commands
and returns to Active mode when disc access is necessary.
1.8 Environmental tolerances
1.8.1 Ambient temperature
Ambient temperature is defined as the temperature of the environment
immediatelysurroundingthedrive.Actual drivecasetemperatureshould
not exceed 65°C (149°F) within the operating ambient conditions. Rec-
ommended measurement locations are shown in Figure 3 on page 20.
Above 1,000 feet (305 meters), the maximum temperature is derated
linearly to 112°F (44°C) at 10,000 feet (3,048 meters).

1.8.3.1 Relative Humidity
1.8.3.2 Wet bulb temperature
1.8.4 Altitude
1.8.5 Shock
All shock specifications assume that the drive is mounted securely with
the input shock applied at the drive mounting screws. Shock may be
applied in the X, Y or Z axis.
1.8.5.1 Operating shock
These drives comply with the performance levels specified in this docu-
ment when subjected to a maximum operating shock of 63 Gs (based
on half-sine shock pulses of 2 msec). Shocks should not be repeated
more than two times per second.
1.8.5.2 Nonoperating shock
The nonoperating shock level that the drive can experience without
incurring physical damage or degradation in performance when subse-
quently put into operation is 350 Gs (based on nonrepetitive half-sine
shock pulses of 2 msec duration).
1.8.6 Vibration
All vibration specifications assume that the drive is mounted securely
with the input vibration applied at the drive mounting screws. Vibration
may be applied in the X, Y or Z axis.

U Series 5 Family Product Manual, Rev. B 13
The following table lists the maximum vibration levels that the drive may expe-
rience whilemeeting the performance standards specified in this document.
1.8.6.2 Nonoperating vibration
The following table lists the maximum nonoperating vibration that the
drive may experience without incurring physical damage or degradation
in performance when subsequently put into operation.
1.9 Drive acoustics
Drive acoustics are measured as overall A-weighted acoustic sound
power levels (no puretones).All measurementsaregenerallyconsistent
with ISO document 7779. Sound power measurements were taken
under essentially free-field conditions over a reflecting plane. For all
tests, the drive was oriented with the cover facing upward.
Note. For seek mode tests, the drive was placed in seek mode only.
The number of seeks per second is defined by the following
equation:
(Number of seeks per second = 0.4 / (average latency + average access time)
5–21 Hz 0.02-inch displacement (peak to peak)
22–350 Hz 0.5 Gs acceleration (zero to peak)
351–500 Hz 0.25 Gs acceleration (zero to peak)
