A magnetic recording and reproduction apparatus includes a rotatable head
cylinder for recording information to, and/or reproducing information
from, a magnetic tape; a tape pull-out member for pulling out the
magnetic tape; and a guide member for guiding the tape pull-out member.
The tape pull-out member is engaged with a groove formed in the guide
member. The tape pull-out member is movable between a first position and
a second position along the groove. The first position is a position at
which information recording to, and information reproduction from, the
magnetic tape is possible. The second position is a position at which
information recording to, and information reproduction from, the magnetic
tape is impossible. The rotatable head cylinder is provided on a cylinder
holding member integrally formed with the guide member. A profile of the
groove is continuous with no gap.
