Introduction

The MTU992119922 magnetictape units, designedfor use

with

DPS 6 PLUS

systems, arebuffered, 9-track, dual-density magnetic tape

units

that

offer

6250-bpi Group CodedRecording(GCR) and 1600-bpi Phase-Encoded (PE) opera-

tion. Eachtape

unit

has

three

operatingperformance modes: 25-ips start/stop,

25-ips streamingmode,

and

75-ips streamingmode. Dependingon

data

flow

between

the

tape subsystem

and

the

host system,

the

unit

automatically selects

the

mode which provides

the

maximumthroughput.

Each

tape

unit

is located

a separatecabinet.

Each
