Each tape unit contains a 128K -byte electronic data buffer, capable of storing
commands and data records. Buffered data is transferred between the host .
c ,
system and the tape unit at the channel data rate which is faster than the typical
tape writing rate. As a result, the tape unit can continue read or write
operatioI,l~
despite short interruptions in data flow with the host system. Many applications
will operate at a much greater throughput rate than with a 75-ips, non-buffered
tape unit.
Unlike many other tape units, the tape units contain no tape capstan with motor
drive, tension arms, or vacuum columns. The tape is driven by reel motors that
are electronically servo-controlled to regulate tape speed and tape tension. The
tape is guided over the read/write head by air bearings that sense tape motion
and tension to help control supply and take-up reel motors.
