Slider spring under "tension-compression"

Spring for a slider, characterized in that it comprises:

• a flexible leaf (30) having a first and a second ends (32,34),
• a pliable strip (40) having electrically conductive tracks (43) and a first and a second ends (42, 44),
• a means (46) for fixing the first end (42) of the pliable strip (40) beneath the first end (32) of the flexible leaf (30), the strip (40) projecting slightly beyond the first end (32) of the flexible leaf (30) in order to form a tongue (48),
• a slider (50) with one or more magnetic heads (51), said slider (50) being fixed beneath the tongue (48), the conductive tracks (43) of the strip being connected to the head (51),
• a shim (54) fixed beneath the second end (34) of the flexible leaf (30) and to the flexible strip (40),
• the pliable strip (40) being under tension between the shim (54) and the fixing means (46) and the flexible leaf (30) under compression, a top to bottom force is thus exerted on the first end (32) of the flexible leaf (30) and consequently on the slider (50),
• the second strip (40) having its second end (44) located behind the fixing shim (54) and at a certain distance (Y) from the latter.
