COPY PTP:←FILE.EXT

This is equivalent to

COPY PTP:←FILE.EXT/BINARY

What happens is that each 36-bit word appears as six 6-bit bytes on the
tape.  The first (left-most or most significant) six bits of the first
word appears first. Each 6-bit byte is written right-justified on the tape
(see below).  LSB of the tape corresponds to the LSB of the 6-bit byte
from the word (i.e. the byte reads from left to right on the tape).  The
parity bit (MSB) on the tape is always on for binary. Thus in binary mode,
the next to left bit is always off (unpunched).

If you need more general treatment, you can say

COPY PTP:←FILE.EXT/ASCII

In this case, the left-most 35 bits are written out as five 7-bit ascii
numbers, right-justified on tape. The LSB of the 36-bit word is ignored. The
MSB of the tape is parity.

General format info and definitions of left and right:

Ones are holes and zeros are non-holes.
The right of the tape is defined as the side having three bits between 
  the edge and the (smaller) sprocket-holes. 
The left side has 5 bits between the edge and the sprocket-holes.
The LSB appears on the right edge of the tape.
