Abstract:
A printed circuit that connects a head to a pre-amplifier circuit of a hard disk drive. The head has a pair of write bond pads and a pair of read bond pads. The printed circuit has a pair of read traces located in a first layer and connected to the read bond pads. The printed circuit also has a pair of write traces that are located in a second layer and connected to the write bond pads. The write traces cross with the read traces so that a head fabricated from a single head wafer can be used as a Up head in a hard disk drive.
