Abstract A magnetic tape cassette including a pressure pad which consists of a pad piece and a leaf spring holding the piece in place, characterized in that the leaf spring is formed, in one piece, of a pad-piece-holding portion supporting the back side of said pad piece, two wing portions and Y-shaped portions extending from the upper and lower edge sections of the both ends of said pad-piece-holding portion and joining said both wing portions is provided. The present pressure pad is capable of exerting a uniform pressure to a magnetic tape against a magnetic recording and reproducing head of a magnetic tape cassette recorder when said cassette is put in position of the recorder and the recorder is placed in the recording or reproducing mode.
A pressure pad assembly for a magnetic tape cassette, said assembly comprising a substantially rectangular pad piece and a one-piece leaf spring for retaining said pad piece relative to a magnetic head having magnetic cores set therein; said leaf spring comprising a generally rectangular retaining portion for supporting the back side of said pad piece; two wing portions connected to opposed edges of said pad retaining portion; Y-shaped portions each having two legs extending from upper and lower sections of said opposite edges of said retaining portion joining the edge sections to said wing portions; the regions where said two legs of each Y portion and said retaining portion are joined together bein aligned with and overlying a core set in such recorder magnetic head.
