摘要： A counter configuration operates in cooperation with a delay configuration such that the counter configuration counts an input interval based on a given clock speed and a given clock interval while the delay configuration provides an enhanced data output that is greater than what would otherwise be provided by the given clock speed. The counter configuration counts responsive to a selected edge in the clock interval. An apparatus in the form of a correction arrangement and an associated method are configured to monitor at least the delay configuration output for detecting a particular time relationship between an endpoint of the input interval and a nearest occurrence of the selected clock edge in the given clock signal that is indicative of at least a potential error in the enhanced data output and determining if the potential error is an actual error for subsequent use in correcting the enhanced data output.

摘要： A method and apparatus for detecting a high fly write condition in a disk drive is disclosed. Amplitudes of automatic gain control (AGC) fields are used in connection with determining whether a high fly write condition exists in a disk drive, since the amplitude of an AGC field read by a head is generally related to the flying height of the head. In one embodiment, a calibration process is performed to obtain average amplitudes of AGC fields on a zone-by-zone basis for a head associated with a disk surface. These average amplitudes of AGC fields are then stored onto the disk surface for later use. When a write operation is to be performed, the head measures the amplitude of the AGC field associated with a data sector onto which a block of data is to be stored. The measured amplitude of the AGC field is compared to the average amplitude of the AGC fields for the zone associated with the AGC field being read. If the difference between the measured amplitude of the AGC field and the average amplitude for the AGC fields for the zone is outside of a certain tolerance, a high fly write condition may exist. Accordingly, data written during a high fly write condition may be rewritten when the flying height has returned to normal or some other remedial action may be taken.
摘要翻译： 公开了一种用于检测磁盘驱动器中的高飞写入状态的方法和装置。 自动增益控制（AGC）场的幅度用于确定磁盘驱动器中是否存在高飞写条件，因为头读取的AGC场的幅度通常与头的飞行高度相关。 在一个实施例中，执行校准处理以获得与磁盘表面相关联的磁头的逐个区域的AGC场的平均振幅。 然后将AGC场的这些平均振幅存储在磁盘表面上供以后使用。 当要执行写入操作时，头部测量与要存储数据块的数据扇区相关联的AGC字段的幅度。 将AGC场的测量幅度与被读取的AGC场相关联的区域的AGC场的平均幅度进行比较。 如果AGC场的测量幅度与该区域的AGC场的平均幅度之间的差异超出了一定的公差，则可能存在高飞写入条件。 因此，当飞行高度恢复正常或可采取一些其他补救动作时，可以在高飞写入状态期间写入的数据被重写。

摘要： An apparatus and associated method are described for use in a disk drive including a disk that that is supported for controlled rotation and for cooperating with a transducer arrangement for accessing the disk in performing a data operation. The disk includes an arrangement of servo track wedge segments for storing servo data such that a set of servo data is periodically available as the disk is rotated in relation to the transducer arrangement and the servo track wedges are separated by an arrangement of user data wedge segments for use in storing user data. Generally, a controller IC and a channel IC are provided. The servo data is transferred from the channel IC to the controller IC using one data protocol and user data is bidirectionally transferred between the channel IC and the controller IC using a different data protocol.

Launch parameters of a golf ball can be characterized independent of any specific positional measurement on the basis of a ball signal that is transmitted from the ball. These parameters include initial spin, initial velocity, and initial trajectory. Ground proximity detection is described as well as a landing position and rollout position detection technique and associated apparatus. Calibration techniques are described for various kinds of range receivers that subsequently receive the ball signal.

摘要： A pulse qualification apparatus and method provides for qualifying signal pulses from a raw data signal by comparison to a variable qualification level. Pulse qualification is done on a read signal developed by moving a magnetic transducer relative to addressable portions of a magnetic disk. A qualification level generator circuit generates a qualification level signal which varies in value depending upon the addressed portion of the magnetic disk. A threshold detector is used in qualifying pulses from a transducer read signal by comparison to the qualification level signal to generate an encoded pulse signal representing occurrences of qualifying pulses.
