摘要： An automatic magnetic tape loading apparatus in a magnetic tape recording/playback system includes a reel support rotatably mounted in a first recess in a base for supporting an open feed reel, a takeup hub rotatably mounted in a second recess in the base for winding a magnetic tape fed from the open feed reel, and a channel defined in the base for passage therethrough of the magnetic tape as it is supplied from the open feed reel to the takeup hub. The base has thereon a plurality of air ducts for blowing air through the first recess and the channel into the second recess to carry a leading end portion of the magnetic tape from the open feed reel via the channel to the takeup hub until the leading tape end portion is coiled around the takeup hub.
