Remote LED Option ----------------- LED (user supplied) connected to Remote LED Both LEDs (on Device Electronics board and remote location) are enabled. Remote LED not connected (default) LED on Device Electronics board enabled. Spindle Synchronization ----------------------- The Rotational Position Locking field (MODE SELECT command, Page Code 04h) is used to specify spindle synchronization operation. Unsynchronized: If the drive is set to Unsynchronized (RPL = 00b), it ignores the SLAVE SYNC signal. Slave: If the drive is set to Slave (RPL = 01b), it does not generate the MASTER SYNC signal or the SLAVE SYNC signal but synchronizes its index to the SLAVE SYNC signal supplied by an external source. Signal termination is placed on the SLAVE SYNC signal at the first and the last device in the chain only. Master: If the drive is set to Master (RPL = 10b), it generates the SLAVE SYNC output signal for use directly by the slave drives. Signal termination is placed on the SLAVE SYNC signal at the first and the last device in the chain only. Master Control: If the drive is set to Master Control (RPL = 11b), it generates the MASTER SYNC signal. This output is used by the controller to generate the SLAVE SYNC signal for the slaves. Signal termination is placed on the SLAVE SYNC signal at the first and the last device in the chain only. ********************************************************************** I N S T A L L ********************************************************************** MICROPL. 4221/4210 TAURUS 2 PRODUCT DESCRIPTION 110791 REV. A 1994 Notes on installation ===================== Recommended mounting orientation -------------------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | | +-----+ +-----+ | +--+ +--+ Dimensions and Mounting ----------------------- The drive uses industry-standard mounting For 3 1/2-inch 1-inch high, Winchester disk drives. Recommended orientation is vertical on either side, or horizontal with the Device Electronics board down; other mounting orientations may be used. No matter what mounting orientation is used, Micropolis specifies that the maximum HDA casting temperature not exceed 60*C (140*F). In order to achieve the HDA casting temperature specified above, forced air flow, around the HDA and Device Electronics board, may be required. For recommended air-flow cooling, refer to the following table: Air Flow | Air Temperature ---------+---------------- 180 LFPM*| 25*C (77*F) * Linear Feet Per Minute 220 LFPM | 50*C (122*F) Mounting Screws --------------- 3 per side 6-32 UNC-2B 4 on bottom 6-32 UNC-2B Caution: The mounting screws must be selected so that they do not penetrate the bottom mounting holes by more than 0.20 inches or the side mounting holes by more than 0.156 inches. Screws that are too long will short to PCBA. SINGLE-ENDED Interface Electrical Characteristics ------------------------------------------------- Interface control and status signals are digital (open collector TTL) using industry-standard transmitters and receivers which provide a terminated, single-ended system. For active termination, the assigned signals are terminated with 110 ohms to +2.85V (nominal). For passive termination, the assigned signals are terminated with 220 ohms to +5V (nominal) and 330 ohms to ground. All signals use open-collector or tri-state drivers. Single-ended drivers and receivers allow a maximum cable length of six meters (primarily for connection within a cabinet). Signal transmission requires a single 50-conductor (flat or twisted-pair) cable. A characteristic impedance of 100 ( 10%) ohms is recommended. a. Input Characteristics Each of the drive's signal receivers has the following characteristics when measured at the interface connector. 1) Low-level input voltage = (Signal true) 0.0 VDC to 0.8 VDC 2) High-level input voltage = (Signal false) 2.0 VDC to 5.25 VDC 3) Low-level input current = -0.4 milliamps at 0.5 VDC 4) High-level input current = 0.1 milliamps at 2.7 VDC 5) Minimum input hysteresis = 0.2 VDC 6) Maximum input capacitance = 25 pF b. Output Characteristics Each driven signal has the following characteristics when measured at the interface connector. 1) Low-level input voltage = 0.0 VDC to 0.5 VDC (signal assertion) 2) High-level input voltage = 2.5 VDC to 5.25 VDC (signal negation) 3) Minimum driver output capability = 48 milliamps (sink) at 0.5VDC c. Terminator Power (TERMPWR at Pin 26) Terminator Power has the following requirements: V(TERM) = 4.25 VDC to 5.25 VDC 800 milliamps minimum source drive capability, with 1.0 amp recommended current limiting (e.g., a fuse). 1.0-milliamp maximum bus loading (except for the purposes of providing power to an internal terminator). The drive provides keyed connectors to prevent accidental grounding or misconnection of terminator power. Signal Connector J1 ------------------- J1 is a 50-pin interface connector. The signals on J1 include the 8-bit SCSI bus and various control and handshaking lines. Recommended Cable: 3M Scotchflex 3365/50 or equivalent. Mating connector: 3M P/N 3425-3000 or equivalent. J1A Power Connector ------------------- J1A is a 4-pin connector used to supply +5V and +12V to the drive.

Temperature Measurement ----------------------- Micropolis specifies the maximum HDA casting temperature to be 60*C (140*F). Not exceeding this temperature will ensure that the head-to- media interface never exceeds its temperature limit. If the HDA casting temperature measurement cannot be made, the ambient air temperature around the drive must be kept at or below 50*C (122*F). ********************************************************************** F E A T U R E S ********************************************************************** MICROPL. 4221/4210 TAURUS 2 PRODUCT DESCRIPTION 110791 REV. A 1994 Description ----------- This Product Description describes the Micropolis TAURUS 2 family of high-performance, 3 1/2-inch, 1-inch high Rigid Disk Drive. The drives provides OEMs with random-access, high-speed, data storage and meet the needs of diverse applications environments. The drives are compatible with the "ANSI CCS" version and the "SCSI-2" version of the industry-standard Small Computer System Interface (SCSI) specification. DIFFERENTIAL INTERFACE IS OPTIONAL. Some Features of the Drive -------------------------- - Positive media protection is achieved during spin down (due to a STOP UNIT command or power off) by automatically retracting and locking the positioner in a data-free landing zone. - N-Segment Read-Ahead algorithm improves read performance by allowing many accesses to be serviced from the cache buffer (512K or optional 2MB). - Optional, Write-Behind Caching provides dramatic improvement in write performance by appending multiple write commands per disk revolution. - In-Line Defect Management (sector slipping) provides maximum throughput. - Data Integrity is ensured with CRC through the buffer, 126-bit Reed-Solomon ECC on-the-fly, and automatic retries using servo and data strobe offsets. Media Defects ------------- Media defects are physical characteristics of the media which result in repetitive read errors when a functional drive is operated within specified operating conditions. At the time of manufacture, a media test system evaluates every drive and identifies each media defect location. The defective areas are identified by head address (HD), cylinder address (CYL), and number of bytes from Index (BFI). The list of manufacturer-found defects is stored on the drive in a reserved, write-protected area accessible by the SCSI controller. This list is known as the MDL (Manufacturers Defect List) or PList (Primary Defect List). The MDL entries can be mapped out (reassigned) automatically at format time by appropriate use of the format control parameter bits. Seek Time --------- ----------------------------------+--------+ Track-to-Track msec. typ. | 1.3 | Average msec. typ. | 8.9 | msec. max. | 21 | Latency msec. avg. | 4.17 | ----------------------------------+--------+ Recording Media --------------- Aluminium disks, each 95 millimeters (3 1/2 inches) in diameter, are mounted on the spindle assembly. The recording surface on each disk is a thin coating of magnetic material, with a carbon over-coat to protect it. Air Filtration System --------------------- The drives are designed to provide contamination control within the HDA throughout the life of the drive with zero maintenance. Air within the HDA is continuously recirculated and filtered through a high efficiency filter. A breather filter protects the HDA from in- ward contamination migration during air pressure changes associated with drive temperature or atmospheric pressure variations. Braking ------- The heads contact an area of the disk surface which is not used for data storage when the disk are not spinning and during start and stop cycles. Dynamic braking is used to stop the spindle quickly. Loadable Code ------------- The drive can electronically download SCSI Firmware via the SCSI interface.
