3.0 GENERAL DESCRIPTION
3.1 Introduction
The Series .5000E streaming tape drive (Figure 1.0) is a family of
innovative, low cost, highly reliable }{.-inch wide cartridge tape
drives.
When utilized in the "streaming" mode at 90 ips, and using a standard
.!t.i,9-foot-long tape cartridge (Figure 1.1) the drive can record 20, or
( ~bytes of data, using the Ii- o;@track format, reseectiveJy•
./ Utilization of the 600-foot-long tape cartridge provides storage of
either 26.7 or 60 Mbytes of data with the 4 or 9 track format,
respectively.
The Series 5000E cartridge tape drive can be utilized for either
Winchester disk backup or general data storage in the streaming
start/stop or data distribution mode.
An optional intelligent formatter, available in either a half-high
module or external to the drive, will record either the QIC-24- or
Archive 8-inch QIC-11 data format using the QIC-02 defined
intelligent interface.
3.2 Physical Description
The drive consists of a die cast aluminum deck. The components
mounted on the deck are as follows:
Head Carriage and Stepper Motor Assemby
Read/Write Head Assembly with integral tape cleaner
Capstan ~otor

Tape Hole Sensor Block Assembly
"Safe" and "Cartridge In" Switch Assembly
The Series 5000E is designed to have the same dimensional
parameters as a 5~-inch Winchester or Floppy Disk drive.
The control electronics are mounted on the deck. The components
are mounted on a 5.7 5-lnch-wide, 1.6-lnch-high, 8-inch-deep envelope
(Basic Interface), and 5.75-inch-wide, 3.25-inch-high, 8-inch-deep
envelope with the intelligent formatter included.
3.3 FWlctional Description
The Series 5000E can utilize either the 450-, or 600-foot tape
cartridge.
The type of cartridge being used is transparent to the user, due to the
drives automatic capability to select the proper write currents and
read gains for the respective cartridge being utilized.
The Series 5000E also utilizes the QIC-24 track reference burst to
automatically position the head to the center of the reference burst.
NOTE: This feature requires that the "Search" jumper be
removed.
The above feature minimizes misalignment of the head when reading
tapes generated by other drives utilizing the QIC-24 data format.
When the Series 5000E tape drive is in the WRITE mode, it will
automatically position the Read/Write head assembly to the
theorectical Track 0 position.
3.4 Drive Microprocessor
The microprocessor employed is the kernel for the device operation,
and maintains control of the stepping mechanism, drive motor, and
decodes all the commands from the formatter.
3• .5 Capstan Motor System
The capstan motor assembly is controlled by the drive
microprocessor. The speed is also monitored by the formatter, which
uses a signal derived from a tachometer. Instantaneous speed
variation is held within + 7 %, while long term speed variation is
limited to !. 3 %.
3.6 Head Carriage and Stepper Motor Assembly
Positioning of the head to the desired track is accomplished by a
stepper motor lead screw positioning mechanism. The drive signal to
the stepper motor is generated by the CPU on the formatter, and
interpreted by the drive microprocessor.

3.7 Read/Write Head Assembly
Reading and writing on the tape in either a 4-, or 9-track format is
performed by a two channel serpentine recording head, arranged with
"read, after write" poles with a full tape erase bar.
3.3 Tape Hole Sensor Assembly
The system for detection of End of Tape (EOT), Beginning of Tape
(BOT), Load Point (LP), and Early Warning (EW) holes utilizes optical
sensor assemblies, the output of which are synchronously clocked into
the formatter's CPU.
3.9 Daisy Chain Capability
The drive may be configured by the user to be constantly selected or
selected by any one of four available discrete select lines. The
selected (SLD) signal is sent to the formatter CPU and the acivity
LED.
3.10 Activity LED Indicator
The acitvity LED is illuminated when the drive is selected and busy.
It is enabled by the select lines in conjunction with the user
selectable DIP shunts.
