Abstract: Provided is a process of compiling user instructions into a JavaScript program, the process including: obtaining a library comprising a plurality of subroutines having a standardized interface and encoded in a human-readable format; obtaining a decision tree, the decision tree containing a declarative representation of business logic to be implemented in a human-readable JavaScript program to be executed server-side in a client-server architecture, the decision tree identifying at least a plurality of the subroutines in the library to be used in the JavaScript program; and compiling the decision tree and the plurality of subroutines into the JavaScript program, wherein compiling comprises: crawling the decision tree and identifying the subroutines; parsing the one or more instructions executed to perform the tasks of the identified subroutines from the respective standardized interface of the identified subroutines; and adding at least part of the parsed instructions to a text representation of the JavaScript

Abstract: The present invention is directed to a disk drive that employs a proximity recording interface in which a slider that carries a head is designed to remain in contact with the disk during data transfer operations to achieve a high data density. In particular, the present invention is directed to cleaning debris from a pad on the slider that carries the head. The debris, if allowed to accumulate, can reach a depth at which the head is spaced from the disk at a distance which adversely affects the transfer of data with the disk. In one embodiment, the spin motor of the disk drive is caused to rotate at a lower angular velocity than during normal data transfer operations, preferably using open loop control, while the actuator of the disk drive is used to radially displace the slider and associated head, also preferably using open loop control. For a constant angular velocity of the disk, the change in radial position causes different areas of the pad to be contacted and cleaned by the disk.
