To write a file into another file, you can write a program. Following snippet is in C.

char buf[512];
int floppy_desc, file_desc;
file_desc = open("xx.bin", O_RDONLY);
read(file_desc, buf, 512);
close(file_desc);

floppy_desc = open("floppy.img", O_RDWR);
lseek(floppy_desc, 512, SEEK_SET);
write(floppy_desc, buf, 512);
close(floppy_desc);
