The winding small tube apparatus comprises an extruded flat tubed strip having a plurality of openings leading to parallel lumens and a header for attaching to an end of this extruded flat tubed strip to cover the openings. Every other portion of the partition at the openings of the lumens disposed in the extruded flat tubed strip is cut away to connect the lumens to form a continuous winding, serpentine sealed channel. By this invention, the manufacturing process is facilitated, the overall height of the apparatus is lowered, and the heat exchange property is raised.

A head exchange system for a disc drive system for controlling the position of a head so as to cancel, during a head exchange, the previously measured offset value between the head and a track of a recording disc. The head exchange system has a head exchanger for selecting one of a plurality of heads in response to a signal from the host controller for storage of the information to the selected track of the disc. The head exchange system also has a busy signal transmitting unit for transmitting, when changing the selected head, a busy signal to the host controller for a predetermined time when a difference between the offset value for a current selected head and the offset value for a next selected head is bigger than a predetermined value. The busy signal transmitting unit has a busy table for storing a plurality of flag information between each head and the other heads and transmits a busy signal to the host controller when the difference between the offset value for the current selected head and the offset value for the next selected head is bigger than the predetermined value.
