First, why is the record button on a tape recorder always Red? Does it have any significant meaning? Also, why does the play button also get activated when you push record? I actually looked inside to see what happenes when you push play and then when you push record. The record process has an extra square-shaped object comming down on the tape (persumably to record), but the play head is a few cm's down from the recording head. Wouldn't this cause echos?
