FCC Notice

This equipment generates and uses radio frequency energy and, if not installed
and used properly; that is, in strict accordance with the manufacturer's
instructions, may cause interference to radio and television reception. It has
been type tested and found to comply with the limits for a Class B computing
device in accordance with the specifications in Part 15 of FCC Rules, which are
designed to provide reasonable protection against such interference in a
residential installation. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause interference
to radio or television reception, which can be determined by turning the
equipment on and off, you are encouraged to try to correct the interference by
one or more of the following measures:

• Reorient the receiving antenna.

• Relocate the computer with respect to the receiver.

• Move the computer into a different outlet so that the computer and receiver
are on different branch circuits.

If necessary, you should consult the dealer or an experienced radio/television
technician for additional suggestions. You may find the following booklet
prepared by the Federal Communications Commission helpful:

What are the Drives?

The CFP4207 series is a family of high performance 3.5-inch half height 4.2GB
(formatted) disk drives. They all offer 9.0 millisecond average seek time for
Reading, 9.5 millisecond seek time for Writing, with an average latency of only

4.17 ms. High capacity is achieved by utilizing a zone density recording
technique using 15 recording zones at an areal density of 317 Mbits per square
inch. These drives feature high performance while maintaining low power
consumption to reduce power supply current and system cooling requirements in
disk arrays.

They are designed to operate on the Small Computer System Interface (SCSI)
and are SCSI-2/3 compatible. The mechanical and major electronic components
are identical between the models and differ only in the host interface
implementation:

Chapter 1 Overview of the Drives

Drive Assembly Housing

The drive assembly housing, or Head-Disk Assembly (HDA) consists of a die-cast
aluminum base on which is mounted a die-cast aluminum cover. Both the base
and the cover are fabricated using an alloy and surface finishing process
designed to inhibit oxidation. A gasket seals the joint between the base and
cover to retard the entry of moisture and environmental contaminants from the
assembly.

This assembly, the head-disk assembly, contains an integral 0.3 micron filter,
which maintains a clean environment. Critical drive components are contained
within this contaminant-free environment. Figure 1-2 shows the HDA and the
major assemblies contained within it:

Overview of the Drives Chapter 1

Drive Motor and Spindle

A brushless DC direct-drive motor assembly is mounted on the drive’s base. The
motor rotates the drive’s spindle at 7200 RPM. The motor/spindle assembly is
dynamically balanced to provide minimal mechanical runout to the disks. A
dynamic brake is used to provide a fast stop to the spindle motor and return the
heads to the landing zone when power is removed.

Head Positioning Mechanism

The read/write heads are supported by a mechanism coupled to a rotary voice
coil actuator.

Read/Write Heads and Disks

Data is recorded on 95mm diameter disks through 3370-type 50% nano-slider
thin film heads with transverse pressure contour (TPC) air bearing surfaces.
The TPC air bearing surface allows the head to fly at a uniform height
regardless of radial position. This improves data reliability and allows the aerial
density to be more uniform with radius. The CFP4207 series contains ten
sputtered thin film disks with twenty data surfaces and twenty read/write
heads.

At power-down, the heads are automatically retracted to the inner diameter of
the disk and are latched and parked on a landing zone that is inside the data
tracks.

Data and Power Connections

Data and power connections to the drive are different between the drive models.
Refer to chapter 4 for information regarding a specific model's requirements.

Electrical Design Features

Integrated Circuit

A single integrated circuit (IC) is mounted within the sealed hard drive assembly
in close proximity to the read/write heads. The IC provides head selection, read
pre-amplification, and write drive circuitry.

Circuit Board

The drive’s dual-microprocessor-controlled circuit board provides the remaining
electronic functions, which include:

• read/write circuitry

• rotary actuator control

• interface control

• spin speed control

• auto-park

• power management

Technical Reference Manual Page 5

Chapter 1 Overview of the Drives

The background processor is a 16-bit Motorola 68HC16. The entire data path
between the serializer-deserializer and the interface chip, including the buffer
(cache) is 16 bits wide to provide high data throughput. The SCSI interface chip
manages a 16-bit to 8-bit conversion prior to transacting data over the SCSI bus
for 8-bit narrow SCSI applications.

The data buffer (cache) utilizes a 256K x 16 Dynamic RAM. Data path integrity
is ensured by using a 4-byte CRC which is appended to the data upon receipt by
the Catalina. This CRC is verified by the buffer manager when the data is taken
out of the buffer to be written to the disk and the CRC is written with the data.
A typical sector data field consists of 512 bytes of data, 4 bytes of CRC and 11
bytes of Error Detection And Correction (EDAC) code. The same CRC checks are
performed during an outbound process and the CRC is stripped from the data
prior to sending it to the Host.

The SCSI interface functions are managed by a 8-bit Motorola 68HC11
microprocessor. Low SCSI transaction overhead is maintained by automating
common SCSI bus phase sequencing using a state machine in the SCSI Interface
Chip.

Firmware

Read/Write Channel

The Read/Write channel, in addition to the preamplifier discussed earlier,
consists of three integrated circuits:

• Pulse Detector

• Data Separator

• Time base

The drive’s firmware can be considered in two parts. The first part principally
resides in the ROM for the 68HC16 background processor. This processor is
responsible for:

• starting the spindle motor and maintaining precise rotational speed

• controlling track following and actuator motion during seeking

• managing background R/W activity

• power management

• monitoring the overall health of the drive.

The interface processor's control microcode resides in both ROM and RAM. The
RAM portion of the microcode can be upgraded in the field with using software.
Additional information regarding the RAM code can be found in Chapter 3, page

22. The interface processor firmware functions include:

• reporting drive status and error conditions to the host

• manage operating parameters for the drive

• parsing the Command Descriptor Block and checking for illegal fields

• converting the LBA to CHS and initiating read and write operations to the

background processor

• defect management

Page 6 Filepro CFP4207 Series

Overview of the Drives Chapter 1

• serial port communications

Since parsing/decoding of commands and execution of the Read/Write functions
are handled by separate processors, command execution can be overlapped in
multiple initiator or Tagged Command Queuing environments. Functions such
as seek re-ordering and command coalescing can also be overlapped when the
drive is operating with a host environment capable of supporting Tagged
Command Queuing.

For more information on the drive’s interface implementation and command set,
refer to the Eleventh Generation SCSI Interface Manual.
