Notes
1. The maximum fixed disk ripple is measured at 3.3 / 5 V input of the drive.
2. The disk drive shall not incur damage for an over-voltage condition of +25% (maximum duration of 20 ms) on the
3.3 / 5-volt nominal supply.
3. The idle current is specified at an inner track.
4. The read/write current is specified at 100% duty.
5. The seek average current is specified based on three operations per 100 ms.
6. The worst-case operating current at unloading.
Interface connector
The interface connector of the Hitachi Microdrive complies with CompactFlash Specification, Revision 1.4.
ATTENTION: The drive must be protected against electrostatic discharge (ESD) especially when
being handled. The safest way to avoid damage is to put the drive in an anti-static bag before ESD
wrist straps are removed.
Drives should only be shipped in approved containers. Severe damage can be caused to the drive if the
packaging does not adequately protect against the shock levels induced when a box is dropped. Consult
your Hitachi representative if you do not have an approved shipping container.

Class 3. Upon receipt of a Class 3
command, the card sets BSY within
400 ns, sets up the sector buffer for
a write operation, sets DRQ within
20 ms (assuming no reassignments),
and clears BSY within 400 ns of
setting DRQ.

Load/Unload heads
When used properly, the Load/
Unload mechanism is designed to
allow 300,000 cycles of starts and
stops. Invoking one of the following
commands unloads the heads:
SOFT RESET
STANDBY
STANDBY IMMEDIATE
The Load/Unload mechanism is also
invoked as one of the idle modes.
After a short period of inactivity the
Adaptive Battery Life Extender
power management will unload the
heads to conserve energy. When
the heads are unloaded, they rest in
a small detent. To prevent the
heads from being thrown off the
ramp during angular acceleration, a
bi-directional, normally open,
mechanical latch engages with the
actuator to keep it from turning in the
head loading direction. This action
causes a “rattle” sound to be heard
which can be mistaken for loose
parts.

Class 1. Upon receipt of a Class 1
command, the card sets BSY within
400 ns.
Most software and operating
systems make use of a disk drive in
bursts. The Hitachi Microdrive monitors the commands sent from the
host to detect patterns which indicate that a command sequence is
finished by putting the drive into low
overall power consumption and
longer battery life with no loss in
performance. If the host system
changes the number or frequency of
the commands sent, the disk drive
automatically adapts to this new
pattern.
This feature has three idle modes:
• Performance idle
• Active idle mode
• Low Power idle

Class 2. Upon receipt of a Class 2
command, the card sets BSY within
400 ns, sets up the sector buffer for
a write operation, sets DRQ within
700 us, and clears BSY within
400 ns of setting DRQ.
Adaptive Battery Life Extender-3
The Adaptive Battery Life Extender-3
(ABLE-3) provides power saving
without performance degradation.
ABLE-3 technology automatically
determines the correct time to start
removing power from the drive
electronics.
To provide the greatest flexibility of
operation with optimum performance
and power consumption, the drive
has a number of operating modes.
These are defined below.
Spin Up
Start up time period from spindle
stop or power down.
Seek

Write
Write operation mode
Read
Read operation mode
Performance idle
The device is capable of responding
immediately to media access requests. All electronic components
remain powered and full frequency
servo remains operational.
Low Power idle
Spindle motor is rotating normally
with actuator unloaded to the parking
positions.
Standby
The device interface is capable of
accepting commands. Spindle motor
is stopped. All circuitry except host
interface is in power saving mode.
The execution of commands is delayed until spindle becomes ready.
Sleep
Same as Standby

Electromagnetic compatibility
When installed in a suitable enclosure and exercised with a random
accessing routine at the maximum
data rate, the drive meets the worldwide EMC requirements of the
United States Federal Communications Commission (FCC) Rules
and Regulations (Class B), Part 15.
This drive is certified for compliance
to EC directive 89/336/EEC.
C-Tick Mark complies with Australian
EMC standard, AS/NZS 3548:1995
Class B.
The drive complies with Taiwan
BSMI.

Cooling requirement
The host system must provide sufficient airflow across the drive to
maintain the temperature at less
than 65°C at the center of the top
cover of the drive.
Operating shock
No data loss or permanent damage
occurs during a half-sine shock
pulse of 1960 m/sec2 of 2-ms
duration and a half-sine shock pulse
of 98 m/sec2 of 11-ms duration.
Non-operating shock
The disk drive must withstand with
no damage a half-sine wave shock
pulse of 1176 m/sec2 of 11-ms
duration and a half-sine wave shock
pulse of 19600 m/sec2 of 1ms
duration on six sides when heads
are unloaded.
Operating and non-operating
vibration
Due to the complexity of this subject
we recommend that users contact
the distributor to discuss how to perform the necessary measurements if
they believe this to be an area which
requires evaluation.
The drive is designed to be used
under the following conditions:
• Levels of shock, vibration, temperature, humidity, altitude, and
magnetic field are within the
specifications.
• Precautions are taken to prevent electrostatic discharge
(ESD).
• The breathing hole on top of the
drive is not covered.
• Pressure is not applied to the
top cover of the drive.
• The drive is operated within the
specification of less than
140 power-on hours per month.
• The Seeking, Writing, and
Reading operations of the drive
constitute no more than 20% of
power-on hours.
• The power requirements of the
drive are satisfied.
• The interface connector is firmly
mated.
• The proper power off sequence
is followed (see the drive specification for further details).
