Abstract: Embodiments of the present invention provide an improved pool. Embodiments of the present invention also provide a method of making an improved pool. The pool can comprise an integrated sidewall joined to a floor portion. The integrated sidewall can be constructed from one piece of material, and can have fewer seams than traditional pools, thereby reducing the likelihood that that pool will rupture and leak. In some embodiments, since the pool has fewer seams than traditional pools, fewer manufacturing steps are required to make the pool. This can increase manufacturing speed and decrease cost.

Abstract: A link writing method for a recordable or rewritable compact disk includes recording a writing interruption address and enabling a succeeding writing process after the writing interruption. Enabling a succeeding writing process includes searching the linking area and enabling a start writing signal and activating a laser power. The method can link a succeeding writing area with a previously written interrupted area with sufficient accuracy to allow the data frame to be successfully processed by error correction within the host drive. The linking area may be positioned by counting the values of the interrupted block, the interrupted data frame, and the interrupted bit count or by detecting a blank area. Other techniques for positioning the linking area include detecting an unwritten area having a length greater than a maximum or writing a characteristic pattern after an interruption.
