W10/W11 Spindle Sync Termination
---------------------------------
Spindle Sync Termination depends on system configuration; i.e.,

W10 and W11 OPEN
Spindle sync is not terminated.
Spindle Synchronization
-----------------------
The Rotational Position Locking field (MODE SELECT command, Page Code
04h) is used to specify spindle synchronization operation.
NOTE
that SSYNC = slave sync and MSYNC = master sync
Unsynchronized: If the drive is set to Unsynchronized (RPL = 00b), it
ignores the SSYNC signal.
Slave: If the drive is set to Slave (RPL = 01b), it does not generate
the MSYNC signal or the SSYNC signal but synchronizes its index to
the SSYNC signal supplied by an external source.
Signal termination is placed on the SSYNC signal at the first and the
last device in the chain only.
Master: If the drive is set to Master (RPL = 10b), it generates the
SSYNC output signal for use directly by the slave drives.
Signal termination is placed on the SSYNC signal at the first and the
last device in the chain only.
Master Control: If the drive is set to Master Control (RPL = 11b), it
generates the MSYNC signal. This output is used by the controller to
generate the SSYNC signal for the slaves.
Signal termination is placed on the MSYNC signal at the first and the
last device in the chain only.
Signal termination is placed on the SSYNC signal at the first and the
last device in the chain only.

Notes on Installation
=====================
Dimensions and Mounting
-----------------------
The drives use industry-standard mounting for 3 1/2-inch, 1-inch
high, Winchester disk drives.
Drive mounting
--------------
horizontally vertically
+-----------------+ +--+ +--+
| | | +-----+ +-----+ |

| +-----+ +-----+ |
+--+ +--+
Recommended orientation is vertical on either side, or horizontal
with the Device Electronics board down; other mounting orientations
may be used.
No matter what mounting orientation is used, Micropolis specifies
that the maximum HDA casting temperature not exceed 60*C (140*F).
CAUTION
The mounting screws must be selected so that they do not penetrate
the bottom mounting holes by more than 0.20 inches or the side
mounting holes by more than 0.156 inches. Screws that are too long
may short to PCBA components.
Mounting Holes: 3 per side, 4 on bottom, 6-32 UNC-2B
Temperature Measurement
-----------------------
Micropolis specifies the maximum HDA casting temperature to be 60*C
(140*F). Not exceeding this temperature will ensure that head-to-
media interface never exceeds its temperature limit.
If the HDA casting temperature measurement cannot be made, the
ambient air temperature around the drive must be kept at or below
50*C (122*F).
J1 Signal Connector

J1 is 50-pin interface connector. The signals on J1 include the 8-bit
SCSI bus and various control and handshaking lines.

Interface Electrical Characteristics
------------------------------------
Interface control and status signals are digital (open collector TTL)
using industry-standard transmitters and receivers which provide
a terminated, single-ended system.
For active termination, the assigned signals are terminated with 110
ohms to +2.85V (nominal). For passive termination, the assigned
signals are terminated with 220 ohms to +5V (nominal) and 330 ohms to
ground. All signals use open-collector or tri-state drivers.
Single-ended drivers and receivers allow a maximum cable length of
six meters (primarily for connection within a cabinet).
Signal transmission requires a single 50-conductor (flat or twisted
pair) cable. A characteristic impedance of 100 ( 10%) ohms is
recommended.
a. Input Characteristics
Each of the drive's signal receivers has the following
characteristics when measured at the interface connector.
1) Low-level input voltage (Signal true) = 0.0 VDC to 0.8 VDC
2) High-level input voltage (Signal false) = 2.0 VDC to 5.25 VDC
3) Low-level input current = -0.4 milliamps at 0.5 VDC
4) High-level input current = 0.1 milliamps at 2.7 VDC
5) Minimum input hysteresis = 0.2 VDC
6) Maximum input capacitance = 25 pF
b. Output Characteristics
Each of the drive's signal drivers has the following
characteristics when measured at the interface connector.
1) Low-level input voltage (Signal assertion) = 0.0 VDC to 0.5
VDC
2) High-level input voltage (Signal negation) = 2.5 VDC to 5.25
VDC
3) Minimum driver output capability = 48 milliamps (sinking) at
0.5 VDC.
c. Terminator Power (TERMPWR at Pin 26)
Terminator Power has the following requirements:
V(TERM) = 4.25 VDC to 5.25 VDC
800 milliamps minimum source drive capability, with 1.0 amp
recommended current limiting (e.g., a fuse).
1.0-milliamp maximum bus loading (except for the purposes of
providing power to an internal terminator).
The drive provides keyed connectors to prevent accidental grounding
or misconnection of terminator power.

DIFFERENTIAL INTERFACE IS OPTIONAL.
Some Features of the Drive
--------------------------
- Positive media protection is achieved during spin down (due to a
STOP UNIT command or power off) by automatically retracting and
locking the positioner in a data-free landing zone.
- N-Segment Read-Ahead algorithm improves read performance by
allowing many accesses to be serviced from the 512K cache buffer.
- Write-Behind Caching, when implemented, provides dramatic
improvement in write performance by appending multiple write
commands per disk revolution.
- In-Line Defect Management (sector slipping) provides maximum
throughput.
- Data Integrity is ensured with interface parity through the buffer,
automatic retries using servo and data strobe offsets, and a 126-
bit Reed-Solomon ECC on-the-fly.
- Optional Set Capacity function allows easy matching of block number
counts for upgrades and emulations.
Media Defects
-------------
Media defects are physical characteristics of the media which result
in repetitive read errors when a functional drive is operated within
specified operating conditions.
At the time of manufacture, a media test system evaluates every
drive and identifies each media defect location. The defective
areas are identified by head address (HD), cylinder address (CYL),
and number of bytes from Index (BFI).
The list of manufacturer-found defects is stored on the drive in a
reserved, write-protected area accessible by the SCSI controller.
This list is known as the MDL (Manufacturers Defect List) or PList
(Primary Defect List).
A printed listing of the defects is also shipped with each drive. The
entries it contains can be mapped out (reassigned) automatically at
format control parameter bits.

----------------------------------+--------+
Recording Media
---------------
Aluminium disks, each 95 millimeters (3 1/2 inches) in diameter, are
mounted on the spindle assembly. The recording surface on each disk
is a thin coating of magnetic material, with a carbon over-coat to
protect it.
Air Filtration System
---------------------
The drives are designed to provide contamination control within the
HDA throughout the life of the drive with zero maintenance. Air
within the HDA is continuously recirculated and filtered through a
high efficiency filter.
A breather filter protects the HDA from inward contamination
migration during air pressure changes associated with drive
temperature or atmospheric pressure variations.
Adjustments and Maintenance
---------------------------
The drive requires no adjustments or periodic maintenance;
additionally, no mechanical adjustments are required to prepare a
system for handling or shipment.
MICROPOLIS AV SERIES
--------------------
Micropolis AV Series disk drives are engineered specifically for
multi-media, high-end graphics, and digital video/audio applications.
With advanced cache management, internal housekeeping improvements,
and enhanced error handling, AV drives provide the highest minimum
sustained data rate in their class. AV drives are designed to provide
a maximum sustained uninterrupted data rate. Unlike data processing
drives, AV drives guarantee a "worst case" data rate performance.
This means that with the buffer empty, the maximum access time
(including error handling) is no more than 30 milliseconds. The
Micropolis 4110AV drive ensures highly predictable data delivery, so
you will never miss a frame or a beat.
