Abstract

Disclosed is a video tape subsystem including VHS-format video tape drive conforming to the form factors of a full-height 5.25-inch DASD (Direct-Access Storage Device) bay of a personal computer and an adapter card attached to the system bus of the computer, providing control and signal interfaces between the computer and the tape deck. This subsystem, which allows the installation of the tape drive within a computer having such a bay available, is particularly useful when the computer is used for video publishing, including the creation and editing of video information, and the interchange of this information using video tape.

Video Tape Drive in a PC Direct-Access Storage Device Bay

      Disclosed is a video tape subsystem including VHS-format video
tape drive conforming to the form factors of a full-height 5.25-inch
DASD (Direct-Access Storage Device) bay of a personal computer and an
adapter card attached to the system bus of the computer, providing
control and signal interfaces between the computer and the tape deck.
This subsystem, which allows the installation of the tape drive
within a computer having such a bay available, is particularly useful
when the computer is used for video publishing, including the
creation and editing of video information, and the interchange of
this information using video tape.

      Fig. 1 is a front elevational view of the video tape drive 10,
which includes a slot 12, into which a video tape cassette 14 is
inserted, end first, an eject button 16 for ejecting the cassette 14,
and seven connectors 18 for making external connections to the unit.
Of these connectors, three are for INPUT lines, three are for OUTPUT
lines, and one is for an external control line.  The INPUT and OUTPUT
connectors each include left and right channels for stereo audio and
a video channel.

      Fig. 2 is a rear elevational view of video tape drive 10, which
includes a power connector 20 and a signal/control connector 22.
Power connector 20 is a four-pin standard power connector, type 2,
for a fixed disk drive.  This power connector is the same type found
on many PC DASD devices.  Signal/control connector 22 is used to
attach the tape unit 10 to an adapter card through a special cable.

      Fig. 3 is a right elevational view of video tape drive 10,
which includes a front bezel 24 and an enclosure 26.  Dimensions
allowing the unit to fit into a full-height, 5.25-inch DASD bay are
shown.
