What are the Drives?
The CFP1060 series are high performance 3.5-inch low-profile (1.0 inch high)
1.06 Gigabyte (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 5.55 ms. High capacity is achieved by utilizing a zone density
recording technique using 9 recording zones at an areal density of 205 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 command compatible. The mechanical and major electronic
components are identical between the models and differ only in the host
interface implementation:

Differences Between the Models
The three drive models differ only on the host interface implementation:
CFP1060E: SCSI 80-pin Wide Single Connector Attachment (SCA) interface
designed for applications such as Redundant Arrays in which the drives are
plugged directly into a backplane. The drive also implements a Wide SCSI
interface for high interface bandwidth.
CFP1060S: SCSI 50-pin standard interface designed for applications which
implement the standard SCSI-2 architecture.

Overview of the Drives Chapter 1
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 coated with a special material designed to seal out
contaminants which might degrade head and media reliability. 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:

Chapter 1 Overview of the Drives
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 5400 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 drive contains four sputtered thin
film disks with eight data surfaces and eight 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 differ 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
The background processor is a 16-bit Motorola 68HC16. The entire data path
between the serializer-deserializer and the interface chip, including the buffer
Page 6 Filepro CFP1060E/CFP1060S/CFP1060W
Overview of the Drives Chapter 1
(cache) is 16 bits wide to provide high data throughput. The "Catalina" 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 "Indy" 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 Catalina chip.
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
Firmware
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
23. 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
• serial port communications
Technical Reference Manual Page 7
Chapter 1 Overview of the Drives
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 Ninth Generation SCSI Interface Manual.
