Recommended Mounting Configuration ---------------------------------- The CP3020 is designed to be used in applications where the units may experience shock and vibrations at greater levels than larger and heavier disk drives. The design features which allow greater shock tolerance are the use of rugged heads and media, a dedicated landing zone, closed loop servo positioning and specially designed motor and actuator assemblies. Ten base mounting points are provided to the customer. The drive is mounted using 6-32 screws;1/8" max. insertion for the sides, and 1/4" max. insertion for the bottom. The system integrator should allow ventilation to the drive to ensure reliable drive operation over the operating temperature range. For additional vibration isolation, an external suspension system may be used. Cable Requirements ------------------ A 50-conductor flat cable or 25-conductor twisted pair cable is re- quired. The maximum cable length is 6.0 meters (19.68 ft). The cable characteristic impedance should be 132 ohms 10% with a minimum conductor size of 28 AWG. Connector Requirements ---------------------- The drive connector is a 50-conductor connector which consists of two rows of 25 male pins on 100 mil centers. The cable connector is a 50-conductor non-shielded connector which consists of two rows of 25 female contacts on 100 mil centers. Power Connector --------------- The drive has a 4-pin DC power connector (J3) mounted on the PCB. The recommended mating connector is AMP part number 1-480424-0 utilizing AMP pins (part number 350078-4 or equivalent). Electrical Description ---------------------- The CP3020 uses open collector drivers. All assigned aignals are terminated with 220 ohms to +5 volts and 330 ohms to ground. The termination resistors are removable for multi-device configurations. SCSI Termination ---------------- There are three removable terminators; RP1, RP2 and RP3. They can be removed from the drive if bus termination is provided elsewhere in the system. Terminator Power ---------------- Terminator power (TERMPWR) is supplied through a diode to prevent the back-flow of power to the drive. TERMPWR has the following character- istics: +--------------------------------+--------------------------------+ |Supply Voltage | 4.0 VDC to 5.25 VDC | +--------------------------------+--------------------------------+ |Minimum Source Drive Capability | 800ma | +--------------------------------+--------------------------------+ |Maximum Sink Capability | 1.0ma sink capability (except | | | for the purpose of providing | | | power to an internalterminator)| | | with a 1.0 amp fuse | +--------------------------------+--------------------------------+ Cabling ------- Connect the power cable to J3. Connect the SCSI interface cable to J2. Bus termination is required on the last device of the SCSI bus. Diagnostic Routines ------------------- The microprocessor performs diagnostics upon application of power. If an error is detected, the drive will not become ready. Magnetic Field -------------- The disk drive will meet its specified performance while operating in the presense of an externally produced magnetic field under the following conditions: +------------------+------------------+ |Frequency | Field Intensity| +------------------+------------------+ | 0 to 700 Khz | 6 gauss maximum| | 700Khz to 1.5Mhz | 1 gauss maximum| +------------------+------------------+ Acoustic Noise -------------- The sound pressure level will not exceed 40 dBA at a distance of 1 meter from the drive. ********************************************************************** F E A T U R E S ********************************************************************** CONNER CP3020 PRODUCT MANUAL 00501-010 Key Features ------------ The Conner Peripherals CP3020 is a 3.5 inch low-profile (1.00") disk drive which offers high performance with low power consumption. Using the Small Computer System Interface (SCSI), which is compatible with the Common Command Set (CCS), the disk drive provides 20 Mbytes of formatted storage. Key features include: - Low power requirements enabling battery operation in portable environments - High performance rotary voice coil actuator with embedded servo system - Two of seven run length limited code - High shock resistance - Internal air filtration system - Sealed HDA - Automatic actuator latch against inner stop upon power-down - Microprocessor-controlled diagnostics routines that are auto- matically executed at start-up - Automatic error correction and retries - Block size: 512 bytes - 8Kbyte data buffer with look-ahead caching - 1:1 Interleave Seek Times ---------- +----------------------------------+--------+ |Track-to-Track msec. | 8 | +----------------------------------+--------+ | Average msec. typ. | 27 | | Average msec. max. | 50 | +----------------------------------+--------+ |Latency msec. avg. | 8.4 | +----------------------------------+--------+ The timing is measured through the interface with the drive operating at nominal DC input voltages. The timing also assumes that the I/O driver overhead and system hardware de- pendency have been subtracted from timing measurements. The average seek time is determined by averaging the seek time for a minimum of 1000 seeks of random length over the surface of the disk. Output Characteristics ---------------------- Each signal driven by the drive has the following output character- istics when measured at the drive connector: +--------------------------------+----------------------------+ |Signal Assertion | 0.0 VDC to 0.4 VDC | +--------------------------------+----------------------------+ |Minimum Driver Output Capability| 48ma (sinking) at 0.5 VDC | +--------------------------------+----------------------------+ |Signal Negation | 2.5 VDC to 5.25 VDC | +--------------------------------+----------------------------+ Input Characteristics --------------------- Each signal received by the drive must have the following input characteristics when measured at the drive connector: +--------------------------------+----------------------------+ |Signal Assertion | 0.0 VDC to 0.8 VDC | +--------------------------------+----------------------------+ |Minimum Total Input Load | -0.4ma at 0.4 VDC | +--------------------------------+----------------------------+ |Signal False | 2.0 VDC to 5.25 VDC | +--------------------------------+----------------------------+ Functional Description ---------------------- The CP3020 disk drive contains all necessary mechanical and electronic parts to interpret control signals, position the recording heads over the desired track, read and write data, and provide a contaminant free environment for the heads and disks. Read/Write and Control Electronics ---------------------------------- One integrated circuit is mounted within the sealed enclosure in close proximity to the read/write heads. Its function is to provide one of two head selection, read preamplification, and write drive circuitry. The single microporcessor-controlled circuit card provides the re- maining electronic functions, which include: - Read/Write Circuitry - Rotary Actuator Control - Interface Control - Spin Speed Control - Dynamic Braking 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. Drive Mechanism --------------- A brushless DC direct drive motor rotates the spindle at 3575 RPM. The motor/spindle assembly is balanced to provide minimal mechanical runout to the disks and to reduce vibration of the HDA. A dynamic brake is used to provide a fast stop to the spindle motor when power is removed. Air Filtration System --------------------- The head-disk assembly is a sealed enclosure with an integral 0.3 micron filter which maintains a clean environment for the heads and disks. Head Positioning Mechanism -------------------------- The two read/write heads are supported by a mechanism coupled to a voice coil actuator.
