The drives feature a low 5V power requirement and high shock resistance, enabling e}battery operation in portable environments.In order for the CP2044 to communicate with the host system, it is necessary ff}or the system to contain a IDE interface. (The IDE interface contains the address decode logic.) This interface may be eig}ther built into the system, or may be placed on a 8 bit or 16 bit I/O card, which can be placed into any open I/O slot withh}in a IBM XT or AT type system.1.1ScopeThis specification describes the key features, specification summary, physical ci}haracteristics, environmental characteristics, functional description, electrical interface, recommended mounting configuraj}tion, and error reporting for the Conner Peripherals model CP2044.2.0Key Featureso2.5" Form factoroSingle 5 Volt sk}upplyoLow power requirementso7.0 ozoHigh performance rotary voice coil actuator with embedded servo system.oSinl}gle connector for power & interfaceoRun length limited code (2/7)oHigh shock resistanceoInternal air filtration systm}emoSealed HDAoAutomatic actuator latch against inner stop upon power downoMicroprocessor-controlled diagnostic routin}nes that are automatically executed at start-upoAutomatic error correction and retriesoBlock size 512 bytesoPC/AT o}interface o1:1 InterleaveoLook Ahead Read Capabilityo32K BufferoMaster/Slave option3.0 Specification Summaryp}3.1Capacity42.6 Mbytes Formatted3.2Physical ConfigurationActuator TypeRotory Voice-coilNumber of Disksq}2Number of Surfaces4Number of Heads4ServoEmbeddedTracks per Surface548Track Density1700 TPIFormatr}ted Track (Bytes)19,456Bytes per Block512Blocks per Drive83,296Sectors per Track383.3PerformanceSeek Tims}esTrack to Track5.0 msAverage19.0 msMaximum40.0Rotation Speed3486 RPMData Transfer Rate1.5 Mbytes pt}er/secStart TimeTypical10 secMaximum20 secStop TimeTypical3.0 secMaximum5.0 secInterleaveu}1:1Buffer Size32KThe timing is measured through the interface with thedrive operating at nominal DC input voltagev}s.

Its func}tion is to provide head selection, read preamplification, and write data circuitry.The single microprocessor controlled ci}rcuit card provides the remaining electronic functions which include:oRead/Write CircuitryoRotary Actuator ControloIn}terface ControloSpin Speed ControloDynamic BrakingoPower ManagementAt power down or the start of STANDBY MODE the hea}ds are automatically retracted to the inner diameter of the disk and are latched and parked on a landing zone that is insid}e the data tracks.6.2 Drive MechanismA brushless DC direct drive motor rotates the spindle at 3486 RPM. The motor/spin}dle assembly is balanced to provide minimal mechanical runout to the disks and to reduce vibration of the HDA. A dynamic bra}ke is used to provide a fast stop to the spindle motor when power is removed, or upon initiation of STANDBY MODE.6.3 Air} Filtration SystemWithin the sealed enclosure, a .3 micron filter provides a clean environment to the heads and disks.6.}4 Head Positioning MechanismThe read/write heads are supported by a mechanism coupled to the voice coil actuator.6.5 R}ead/Write Heads and DisksData is recorded on 65mm diameter disk through micro miniature thin film heads.6.6 Error Corre}ctionThe CP2044 uses a Reed-Solomon code to performs error detectionand correction. The error correction polynomial is cap}able of correcting one error burst with a maximum of 22 bits per 512 byte block. 6.7 Customer OptionsThe CP2044 can op}erate either as a master (C Drive) or a slave (D Drive) depending on the state of jumpers and the setting of Bit 4 in the f}eature byte. When the feature Byte, bit 4, is active (1), and E1 is jumpered, the drive will assume the role of master. Wh}en E1 is open the drive will assume the role of a slave (D drive).7.0 Interface ConnectorThe CP2044 has a 44 pin right a}ngle interface/power connector mounted on the PCB. The recommended mating connector part number from Elco Corporation for }the Flat Ribbon type is 20-8394-2050-02101S; and for the Solder Tail type it is Vertical PCB 20-8390-2050-00101. T}he maximum cable length is two feet. 7.1 Diagnostic RoutinesThe microprocessor performs diagnostics upon application of} power. If an error is detected, the CP2044 will not come ready.8.0 Recommended Mounting ConfigurationThe CP2044 drive} is designed to be used in applications where the unit may experience shock and vibrations at greater levels than larger an}d heavier disk drives.The design features which allow greater shock tolerance are the use of rugged heads and media, a ded}icated landing zone, closed loop servo positioning and specially designed motor and actuator assemblies.Four (4) side mou}nting points and four (4) bottom mounting points are provided to the customer. The drive is mounted using3mm x 0.5mm thread} screws. The screw insertion depth should notexceed 4mm into the mounting holes. The system integrator should allow ven}tilation to the drive to ensure reliable drive operation over the operating temperature range. The drive may be mounted in }any attitude.For additional vibration isolation, an external suspension system may be used. 9.0 Electrical Description}9.1 Signal LevelsAll signal levels are TTL compatible.
