The present invention overcomes the above men

method for a double-deck VCR, in which desired pro
grams of a tape of the ?rst deck are automatically cop
ied to a tape of the second deck by detecting the posi 55
tion of the desired programs on the tape of the ?rst deck
according to selected numbers for the programs.
According to one aspect of the present invention,
there is an automatic copy apparatus of a double-deck
VCR which can perform both the record and the play
back modes, the apparatus comprising a ?rst deck and a
second deck, a keyboard having a mark service key for
generator 20 and subsequently displayed on the display
25.
FIGS. 2A, 2B and 2C show ?owcharts for explaining
the method of controlling the automatic copy apparatus
of a double-deck VCR according to the present inven

In order to select only desired programs among many
programs in the tape of the ?rst deck 30 and then to
copy them to the tape of the second deck 35, the display
as shown in FIG. 3A is displayed by user selection of
the mark service key and the program numbers shown 60
in FIG. 3B are assigned by the user selecting the num

programs by the ?rst process P1, a playback mode is
performed by the second process P2.
In the process P2, step S13 determines whether the 65
