Recommended Mounting Configuration ---------------------------------- The drive is designed to be used in applications where the unit may experience shock and vibrations at greater levels than larger and heavier disk drives will tolerate. 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 x 1/8" max. insertion for the sides, and 1/4" insertion for the bottom. The system integrator should allow ventila- tion to the drive to ensure reliable drive operation over the opera- ting temperature range. 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 mounted on the PCB. The recommended mating connector is AMP part number 1-480424-0 utilizing AMP pins, part number 350078-4 or equivalent. 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 1.5 Mhz| 1 gauss maximum| +------------------+------------------+ Acoustic Noise -------------- The sound pressure level will not exceed 40 dBA at a distance of 1 meter from the drive. Drive Mechanism --------------- A brushless DC direct drive motor rotates the spindle. The motor/ spindle assembly is dynamically balanced to provide minimal mechanical runout to the disk. 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. 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. 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 interminator) | | | with a 1.0 amp fuse | +--------------------------------+--------------------------------+ Screws ------ Side: 4x 6-32 UNC-2B .19 max. screw depth, both sides Bottom: 4x 6-32 UNC-2B .25 max screw depth ********************************************************************** F E A T U R E S ********************************************************************** CONNER CP31370 PRELIMINARY PRODUCT MANUAL REV. A, 10/1992 Key Features ------------ The CP31370 is a high performance 3.5 inch 1.37 Gigabyte (formatted) disk drive. The CP31370 offers 10 millisecond average seek time, an average latency of only 5.55 ms. It achieves its high capacity by utilizing a zine density recording technique using 8-zones. The CP31370 has a data transfer rate of 3.22 MB per second (sustained weighted average) with a burst rate of 10 MB per second. The drive offers high performance while maintaining low power consumption to reduce power supply current and system cooling requirements in disk arrays. It is designed to operate on the Small Computer System Interface (SCSI) and is SCSI-2 command compatible. Automatic Spindle Synchronization 256K Segmentable Cache Buffer 88 Bit Reed-Solomon EDAC with single burst on-the-fly error correction Rotary voice coil actuator with embedded servo system. Automatic actuator latch against inner stop upon power down with dedicated landing zone Redundancy carried on data from interface through to disk SCSI-2 Compatibility Sealed HDA LRU Caching Algorithm Down-loadable Code through SCSI command Programmable Block Size (512-520, 1024 in 2 byte iterations) Command Queuing and Coalescing Seek Times ---------- +----------------------------------+--------+ |Track-to-Track msec. | 2 | +----------------------------------+--------+ | Average msec. typ. | 10 | | Average msec. max. | 18 | +----------------------------------+--------+ |Latency msec. avg. | 5.55 | +----------------------------------+--------+ The timing is measured through the interface with the drive operating at nominal DC input voltages. 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. Functional Description ---------------------- The 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 head selection, read pre-amplification, and write drive circuitry. The microporcessor-controlled circuit card provides the remaining 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 dia- meter of the disk and are latched and parked on a landing zone that is inside the data tracks. 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 disk through TPC type thin film heads. Error Correction ---------------- The Error Detection and Correction (EDAC) implementation in this generation of Conner disk drives is a Reed Solomon code with single burst on-the-fly correction capability. The code will correct any single burst of up to 11-bits in length on-the-fly. The code will correct two error bursts of up to 11-bits in length in firmware and detect three error bursts of up to 11-bits in length. The single burst detection capability of the code is 51-bits.
