Abstract:
A computer system comprising:a host; and a disk drive connected to the host, the disk drive comprising: a disk having a disk surface, the disk surface having a plurality of tracks arranged in an embedded servo format including servo track segments for storing servo data and data track segments for storing user data; read means for reading the servo data and the user data from the disk surface, the read means being operative during a user-data read operation to produce a time-multiplexed analog read signal that during a revolution of the disk represents analog read servo data during each of a first set of time intervals and represents analog read user data during each of a second set of time intervals; a controller including a controller port; a channel integrated circuit chip including: a. an input for receiving the time-multiplexed analog read signal; b. signal processing means for processing the time-multiplexed analog read signal to generate data symbols representing recovered servo data and recovered user data; and c. a channel port; a communication bus connected between the channel port and the controller port; the channel port transferring both the recovered servo data and the recovered user data to the communication bus; the communication bus transferring both the recovered servo data and the recovered user data to the controller port.
