1.5 Seek time
All seek times are measured using a 486 AT computer (or faster) with an
8.3 MHz I/O bus. The measurements are taken with nominal power at
sea level and 25°C ambient temperature. All times are measured using
drive diagnostics. The specifications 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.
•Averageseektimeisatruestatisticalrandomaverageofatleast5,000
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.
Seek type Seek (msec, typ.) Read (msec, typ.) Write (msec, typ.)
Track-to-track 2.0 2.5 3.5
Average 12.0 12.5 14.5
Full-stroke 23.5 24.0 25.0
Average latency: 6.67 msec
Note. This drive is designed to consistently meet the seek times repre-
sented in this manual. Physical seeks, regardless of mode (such
as track-to-track and average) are expected to meet or exceed
the noted values. Due to the manner in which this drive is for-
matted, however, benchmark tests that include command over-
head or measure logical seeks may produce results that vary
from these specifications.

1.7 Power specifications
The drive receives DC power (+5V or +12V) through a four-pin standard
drive power connector.
1.7.1 Power consumption
Powerrequirementsfor thedrivearelistedin thetable below.Typical power
measurements are based on an average of drives tested under nominal
conditions, using 5.0V and 12.0V input voltages at room temperature.
Spinup current is measured from the time of power-on to the time that
the drive spindle reaches operating speed.
During seek mode the read/write actuator arm moves toward a specific
position on the disc surface before executing a read or write operation.
Servo electronics are active. Seek mode poweris measured through the
drive’s serial port while the drive executes a series of sequential seeks.
Operating power and current are measured using 40% random seeks,
40% read/write mode (1 write for each 10 reads), and 20% drive inactive.
Idle mode power is measured with the drive up to speed, servo electron-
ics are active, and the heads are left in a random track location.
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.

1.7.1.1 Typical current profile
Figure 1 shows a typical current profile for the Medalist 3240 and the
Medalist 2531.
1.7.2 Conducted noise
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 120 mV peak-to-peak triangular-wave injected noise at up to 25
MHz.
•Using 5-volt power the drive is expected to operate with a maximum
of 100 mV peak-to-peak triangular-wave injected noise at up to 25
MHz.
Note. Equivalent resistance is calculated by dividing the nominal volt-
age by the typical RMS read/write current.

1.7.4 Power-management modes
This drive provides programmable power management to provide
greater energy efficiency. In most systems, you can control power
management through the system setup program. This Seagate drive
features several power-management modes, which are summarized in
the following table and described in more detail below:
Mode Heads Spindle Buffer
Active Moving Rotating Enabled
Idle Move every 3 minutes Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled
Active mode. The drive is in Active mode during the read/write and seek
operations.
Idle mode. At power-on, the drive sets the idle timer to enter Idle mode
after 5 seconds of inactivity. You can set the idle timer delay using the
system setup utility. InIdle mode, the spindle remains upto speed. Every
3 minutes, the drive performs a random seek. The buffer remains
enabled, and the drive accepts all commands and returns toActive 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 system-
dependent and is usually established using the system setup utility. In
Standby mode, the buffer remains enabled, the heads are parked and the
spindle is at rest. 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
Immediate command from the host. The heads are parked and the
spindle is at rest. The drive leaves Sleep mode after it receives a Hard
Reset or Soft Reset command from the host. After receiving a soft reset,
the drive exits Sleep mode and enters Standby mode with all current
emulation and translation parameters intact.
Idle and standby timers. The drive sets the default time delay for the idle
timer atpower-on.In most systems, you can set thisdelay using thesystem
setup utility. Each time the drive performs anActive function (read, write or
seek), the idle and standby timers are reinitialized and begin counting down
from their specified delay times to zero. If the idle timer reaches zero before
10 Medalist 3240 and Medalist 2531 Product Manual, Rev. A

any drive activity is required, the drive makes a transition to Idle mode.
If the host has set the standby timer, the standby countdown continues.
If the host has not set the standby timer, the drive remains in Idle mode.
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.

ated linearly to 112 °F (44°C) at 10,000 feet (3,048 meters). Oper-
ating ambient temperature is defined as the temperature of the

1.8.5 Shock
For all shock specifications, it is assumed that the drive is mounted
securelywiththeinputshockappliedatthedrivemountingscrews.Shock
may be applied in the X, Y or Z axis. For the nonoperating specifications,
it is assumed that the read/write heads are positioned in the shipping
zone.
Note. At power-down, the read/write heads automatically move to the
shipping zone. The head assembly parks outside of the maxi-
mum data cylinder. When power is applied, the heads recalibrate
to Track 0.
1.8.5.1 Operating shock
The Medalist 3240 and the Medalist 2531 will comply with the performance
levels specified in this document when subjected to a maximum operating
shock of 5.0 Gs (based on half-sine shock pulses of 11 msec, as specified in
MIL-STD-202F). Shocks are not to 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 sub-
sequently put into operation is 75 Gs (based on nonrepetitive half-sine
shock pulses of 11 msec duration, as defined in MIL-STD-202F).
1.8.6 Vibration
For all vibration specifications, it is assumed 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. For the nonoperating
specifications, it is assumed that the read/write heads are positioned in
the shipping zone.
1.8.6.1 Operating vibration
The following table lists the maximum vibration levels that the drive may
experience while meeting the performance standards specified in this
document.
