An information playback apparatus includes a clock combining circuit having a FIFO circuit, a signal combining circuit and a signal selecting circuit. The FIFO circuit accepts, for example, a positive-edge playback signal RDATA0 that has as data the positive edge of a playback signal obtained from recording domains formed in a recording medium, RDATA0 being synchronized with a positive-edge clock signal RCLK0. The FIFO circuit also accepts a negative-edge playback signal RDATA1 that has as data the negative edge of the playback signal, RDATA1 being synchronized with a negative-edge clock signal RCLK1. The FIFO circuit causes RDATA0 and RDATA1 to be synchronized with RCLK0 so as to output a delayed positive-edge playback signal RDATA0D and a delayed negative-edge playback signal RDATA1D. The delayed negative-edge playback signal is delayed by -KT to +LT, where K and L are integers and T is the clock period. The signal combining circuit combines the delayed positive-edge and negative-edge playback signals, and outputs (K+L+1) combined signals.

The present invention includes a method and apparatus for reducing the width of a mark written in optical media. When forming a long mark, the prior art recording methods typically cause blooming at the edges of the mark, resulting in a wide mark pattern which may be sensed by the read focused spot reading an adjacent track causing increased adjacent track crosstalk (ATC). However, by removing every other pulse from the write pulse waveform, the cooling sequence of the writing process is sufficiently increased to allow for additional cooling between pulses. When forming marks with less pulses, the effects of blooming are substantially reduced. Thus, because of the reduction in the effect of blooming, the problems associated with ATC, whereby adjacent track information is recorded, is substantially reduced.

An indication from a live agent in a communication session with a user to invoke a specified automated agent interactive conversation flow is received. The communication session with the user is transitioned from the live agent to the specified automated agent interactive conversation flow. During the specified automated agent interactive conversation flow, the live agent retains control over the communication session. An indication of an interaction of the user with the specified automated agent interactive conversation flow is provided. The communication session with the user is returned back to the live agent.
