A tape handling mechanism and horizontal storage bin for a continuous loop of magnetic tape includes slotted tape guides positioned at critical angles to achieve a smooth and uniform passage of tape from the bin onto a pair of separately operable sprocket drives, past read and write heads tangential to the sprocket drives, and from the sprocket drives back into the bin, while preventing gripping or jamming of the tape loop in the confined bin. A pair of tape guide slots between the read and write heads guides tape into a buffer loop whenever data is recorded by the write head more rapidly than recorded data is read out by the read head. A first tape tension switch operates when the buffer loop is too tight, to cause the write head sprocket to advance tape without recording data, while a second tape tension switch prevents further operation of the recording head sprocket when the buffer store is completely filled.
