1.0 Specification summary

Note. Throughout this manual the Medalist 630xe is referred to by its

model number, ST3630A.

1.1 Format configuration

The drive is low-level formatted at the factory. You do not need to
low-level format the drive.

You can operate the drive using many different address configurations,
provided the number of sectors per track does not exceed 63. The
following tables show Enhanced Cylinder Head Sector (ECHS) and
Logical Block Address (LBA) translation geometries for the standard
configurations. You can verify the parameters using the Identify Drive
(EC

) command.

1.5 Seek time

All performance measurements are taken using a 25-MHz 486 AT
computer (or faster) with an 8.3-MHz I/O bus. The measurements are
taken using nominal power at sea level and at 25°C ambient temperature.
The specifications in the table on page 3 are defined as follows:

• Track-to-track seek time is an average of all possible single-track
seeks in both directions.

• Average seek time is a true statistical random average of at least
10,000 measurements of seeks between random tracks, less over­head.

Medalist 630xe ATA Product Manual, September 1995 3

• 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 average is determined by measuring 100
full-stroke seeks in both directions.

1.7 Power specifications

Except during a write operation, you can apply power to the drive or
remove power from the drive in any sequence without losing data or
damaging the drive.

1.7.1 Power-management modes

The drive supports the following power-management modes:

• Active mod e. The drive is seeking, reading or writing.

• Idle mod e. When the drive rec e ives an Idle Imm e diate com mand, or

the idle timer counts down to zero, the drive enters the Idle mode. In
Idle mode, the spindle remains up to speed. The segmented cache
remains enabled, and the drive accepts all com mands and returns to
the Active mode whenever a seek, read or write operation is needed.

• Standby mod e. When the drive receives a Standby Immediate com ­mand, or the standby timer has counted down to zero, the drive enters
the Standby mode. In the Standby mode, the segmented cache
remains enabled, the heads are parked in the shipping zone and the
spindle is stopped. The dr ive accepts all c ommands and r eturns to the
Active mode whenever a seek, read or write operation is needed.

• Sleep mo de. When the drive receives a Sleep Immediate command,
it enters the Sleep mode. The heads are parked in the shipping zone
and the spindle is at rest. A hard reset or a soft reset returns t he drive
to Active mode. A soft reset preserves the current emulation and
translation parameters.

1.7.1.1 Idle and Standby timers

The drive can enter the Idle mode or the Standby mode by eit her of tw o
methods:

• The computer sends an Idle Immediate command or a Standby
Immediate command.

• The idle timer or the standby timer counts down to zero.

The Idle and Standby timers are disabled at the factory. Use the com­puter’s setup utility to enable and set the timer delays. When the Idle
timer is enabled, it is initialized each time the drive completes a read,
write or seek.

If the Idle timer reaches zero before any drive activity is required, the
drive goes into the Idle mode, and the Standby timer, if it is enabled, is
initialized. If the Standby timer reaches zero before any drive activity is

Medalist 630xe ATA Product Manual, September 1995 5

required, the drive goes into the Standby mode. See the

Interface Reference Manual

, publication number 36111-

Seagate A T A

xxx

for details.

In both the Idle and Standby modes, the driv e accepts all com mands and
returns to the Act ive mode any time disc access is necessary . There may
be a slight delay between the time the drive receives the command an d
drive activity begins.

1.7.1.2 Power consumption

The following guidelines are used to measure power consumption:

• All measurements are taken at sea leve l with an ambient temperature
of 25° C.

• All typical measurements are taken us ing nominal v oltages; the peak
startup power is measured using the nominal voltages.

• Seek current measurements are taken using an RMS meter while th e
drive is randomly seeking with two spindle rotations between each
seek.

1.7.3 Conducted noise

The drive is expected to operate with a maximum of:

• 150 mV peak-to-peak triangular-wave injected noise at the power
connector. The frequency is 10 Hz to 100 KHz with equivalent resistive

loads.

• 100 mV peak-to-peak triangular-wave injected noise at the power
connector. The frequency is 100 KHz to 10 MHz with equivalent
resistive loads.

1.7.4 Environment

The acceptable environmental conditions for the drive are specified
below . The specific ations in this section are defined as follows:

• Operating specifications assume that the drive is powered up.

• Nonoperating specifications assume that the drive is packaged as it

was shipped from the factory.

1.7.5 Ambient temperature

Operating 5° to 55° C (41° to 131°F)
Nonoperating –40° to 70° C (–104° to 158°F)

1.7.6 Temperature grad ien t

Operating (max) 20°C per hour (36°F per hour)
Nonoperating (max) 30°C per hour (54°F per hour)

4. Equivalent resistance is calculated by dividing the respective voltage by the typical RMS
read/write current.
